404 Not Found in Joomla Administrator - JSecure

This is one common solution if you're getting a "404 Not Found" error when visiting your Joomla administrator area. The problem often lies with a good and useful product called JSecure. You normally have to remember a specific URL that was set in the administrator area. For example: mysite.com/administrator?mysecretcode. This stops people from trying to guess your login, but if you forget your secret code ...

Do you see this screen?

If you do, the problem is JSecure. Have you really forgotten your secret code? If so, read on ...

Login to Your Hosting Account

tutuploadsmedia_1272638486132.png

Or you could go via FTP. Essentially you just need a way to get to your files.

Find Your File Manager

tutuploadsmedia_1272638559684.png

Every hosting company should give you access to your files, although the access may be in different places with each host. This is an example from the popular CPanel software.

Browse to /Plugins/System/

tutuploadsmedia_1272638742315.png

You need to access the /plugins/ folder than then the /system/ folder.

Find JSecure.php

tutuploadsmedia_1272638817604.png

Rename the File

tutuploadsmedia_1272638910923.png

Just give jsecure.php a different name and save it. Next time to try to access your site, the 404 error should have gone.

Find and Edit Joomla CSS Problems

This purpose of this tutorial is to show you how to find and fix problems with your Joomla templates. We're going to focus on CSS (or Cascading Style Sheets) because they control very common issues such as fonts, colors and padding.

Download and Install Firefox

tutuploadsmedia_1272633877883.png

No question about it, Firefox is the best tool you can find for fixing problem on your website. Download from https://www.mozilla.com/firefox and install.

Install the Web Developer Plugin

tutuploadsmedia_1272633999346.png

Firefox is useful for the same reason as Joomla ... it has 1000s of amazing addons. The one we're going to use is called "Web Developer". Visit https://addons.mozilla.org/en-US/firefox/addon/60 in your Firefox browser and click "Add to Firefox".

Visit Your Joomla Site

tutuploadsmedia_1272634190531.png

We're going to use the default Joomla for this tutorial.

Diagonse Your Problem

tutuploadsmedia_1272634282384.png

In this example, our welcome message is too small. We'd like to have "Welcome to the Frontpage" in larger text.

Start the Webdeveloper toolbar

tutuploadsmedia_1272634412205.png

Click "CSS" in the toolbar and then click "View Style Information"

Click the item you want to edit

tutuploadsmedia_1272634541732.png

Hover your mouse over any part of the page and a red box will appear around it. Click on that area.

See the CSS Code at the bottom of the page

tutuploadsmedia_1272634659128.png

At the bottom of the page you'll get a lot of information about why that item on your site looks like it does. Here's what's controlling the "Welcome to the Frontpage" line:
1: The file with it's exact location
2: The exact line number inside that file
3: The code at that line number
In this case you can see that the font-size is 1.5em. We'll need to increase that number.

Login to Your Joomla Site

tutuploadsmedia_1272634994062.png

Go to Extensions >> Template Manager inside your site

Click on Your Template Name

tutuploadsmedia_1272635089404.png

Click "Edit CSS"

tutuploadsmedia_1272635142542.png

Open Your Template' CSS File

tutuploadsmedia_1272635315354.png

Browse down to find the template you saw in the previous step called "Find the CSS code at the bottom of the page". Click "Edit" in the top-right corner.

Copy Your Test into an Editor

tutuploadsmedia_1272635529610.png

I'm using Notepad in this example, but any text editor will do. If you have a code editor with line numbers, even better!

Backup, backup, backup, backup, backup, backup!!!

tutuploadsmedia_1272635612434.png

If you're doing this for the first time, you will make mistakes. Backup your file so that you can roll back those mistakes when they happen.

Find Your Code to Change

tutuploadsmedia_1272635729434.png

Search for the code that you find earlier in the tutorial.

Change the Code

tutuploadsmedia_1272635783420.png

Especially when you're getting started, this may involve some trial and error. In this example, I'm going to increase the font-size from 1.5 to 1.7.

Paste Back into Your Joomla Site

tutuploadsmedia_1272635839610.png

Paste the code back into your Template Manager and click "Apply".

Check the Change

tutuploadsmedia_1272636023502.png

Great - in this case the change worked and text is larger. If you the change isn't just what you want, you'll need to go back a few steps to "Change the Code" and try again.

Some Notes

1) This is a process of trial-and-error. Don't expect to get it right first time, ever time.
2) Make one change then check. Make one change then check. If you do that, it's easy to spot a mistake. However, if you make wholesale changes before checking, it will be very difficult to find where you went wrong.
3) If you want to move faster, get an FTP Editor that will allow you to edit this files more quickly and accurately. That however, is for another tutorial :)

Change Joomla htaccess.txt file to .htaccess with CPanel

Changing your htaccess.txt file to .htaccess is important in Joomla because it allows you to enable Search Engine Friendly URLs. It's also an important step to help keep your site safe. Here's how to do it.

UTF-8 in Joomla

Have you ever browsed to a website only to find that half the content is unreadable? Or that certain characters are being displayed in strange and mysterious ways? Or perhaps you wanted to enter a foreign or unusual character but found that the result was a garbled mess.

The chances are you have been subject to poorly managed character encodings. Joomla! extensions are no exception to these occurrences, but with a little bit of effort and some help from the Joomla! framework, we can avoid these problems with relative ease.

Place Joomla Images and Videos in a Pop-up

Joomla RokboxThis tutorial was requested by a Joomla training student in our forum. They wanted to make images and videos on their site more interesting by showing them in a pop-up.

Our advice was to try Rokbox from Rockettheme. This extension can place images, videos, audio files, flash files or even entire websites inside a pop-up. This plugin is also available for WordPress.

We're going to show you several ways to use Rokbox on your site:

Installing Rokbox

  1. Rokbox can be downloaded from the downloads section of Rockettheme.com.
  2. Download both the "Content" and the "System" plugins. If you're using Joomla 1.5, download the top two files. They will be named:
    • Rokbox Content Plugin
    • Rokbox System Plugin
  3. In your Joomla site, go to Administrator >> Extensions >> Install / Uninstall and upload both.
  4. Go to Administrator >> Extensions >> Plugin Manager and enable both.

Testing Rokbox

The normal way of using Rokbox will only work inside articles. Try using this simple example as a test:

{rokbox}images/save.png{/rokbox}

That should place Joomla's save button inside a pop-up for you and also generate a thumbnail for you to click on.

If that doesn't work, you may have a problem with generating thumbnails automatically. You can then try one of these two options:

  • Use a text link: {rokbox title=|click here|}images/save.png{/rokbox}
  • Use your own image: {rokbox thumb=images/save.png}images/save.png{/rokbox}

Using Rokbox in Articles

There are lots of examples on the Rockettheme demo site: Rocketwerx.com. These are very simple examples to get you started:

  • Remote images: {rokbox}https://www.ostraining.com/logo.png{/rokbox}
  • Audio files: {rokbox}images/audio/example.mp3{/rokbox}
  • Flash files: {rokbox}images/flash/example.swf{/rokbox}
  • Youtube videos: {rokbox}https://www.youtube.com/watch?v=4BY40QvWQKE{/rokbox}
  • Another website: {rokbox}https://www.google.com{/rokbox}

Using Rokbox Outside of Articles

You can use Rokbox in your other extensions. The only thing you need to do is modify your links so that they contain rel="rokbox".

For example < a href="https://google.com" > becomes < a href="https://google.com" rel="rokbox" >  (I've added a space after each < and before each > so you can see the code)

We've used this technique inside many different extensions.

Configuring Rokbox

There are three places where you can configure options for Rokbox:

1) Inside Extensions >> Plugin Manager >> Content - RokBox

Here you can change the settings for the thumbnails that Rokbox generates automatically:

Roxbox Content Plugin

2) Inside Extensions >> Plugin Manager >> System - RokBox

Here you can select from several different themes for Rokbox. The default is "Light" which provides a white background, but there are others:

Roxbox System Plugin

If you enable "Legacy Parameters", you'll also get a much wider range of options. Full documentation on those is available on the Rocketwerx site.

3) For Individual Pop-Ups

We saw some examples earlier. Here are some ways you can modify individual pop-ups:

  • Set files sizes: {rokbox size=|400 100|} ... this will show an image, flash or video file as 400px wide and 100 high.
  • Set website sizes: {rokbox size=|65% 80%|} ... this will show a website as 65% of it's normal width and 80% of it's height.
  • Custom thumbnail: {rokbox thumb=|images/example.jpg|} ... so you don't have to use the one automatically generated by Rokbox.
  • Custom title: {rokbox title=|This is a cool image|} ... this is what people will click on to see the pop-up, or if there's a thumbnail, this is what they will see if they hover their mouse over the thumbnail.
