One of our customers asked how to hide the menu titles from their OSMap HTML sitemap.
By default, the HTML sitemap groups links under the title of each Joomla menu. Some site owners like this because it organizes the links. Others prefer a cleaner sitemap without the menu headings.
Fortunately, OSMap makes this easy. You can hide the menu titles while keeping every sitemap link visible.
In this tutorial, we'll show you how to do it in just a few minutes.

Google News can be an excellent source of traffic for news websites.
To help Google discover your latest articles, you can submit a Google News sitemap. This is a specially formatted XML sitemap that includes news-specific tags and only lists articles published during the last two days.
A Google News sitemap does not guarantee that your articles will appear in Google News. Instead, it helps Google discover your latest news content more quickly.
In this guide, we'll show you how to create a Google News sitemap for your Joomla site using OSMap.

- Installing OSMap Free resulted in nothing more than a 406 Not Acceptable error.
At first glance, it looked like a Joomlashack Framework issue. By the end of the investigation, however, we discovered that neither Joomlashack nor Joomla was responsible.
