Using SEF URLs breaks all templates

Question

I changed both Search Engine Friendly URLs to Yes and Use URL Rewriting to Yes in Global Configuration and renamed the .htaccess.txt to .htaccess .

But, now none of my templates work anymore.

I have success in making the URLs cleaner (removing the index.php from them), but the templates break. The links work without any problem.

I tried to follow some tutorials without success:

1. https://docs.joomla.org/Enabling_Search_Engine_Friendly_(SEF)_URLs_on_Apache
2. http://www.viryatechnologies.com/Virya-Blogs/joomla-content-management-system/2012/11/29/removing-indexphp-from-existing-sef-urls.html

I believe the mod_rewrite module is not the problem because the "new" links work properly.

The site is hosted in a webserver using Apache. The Joomla version is 3.6.5 .

Does anyone have any idea about what can be happening?

Answer 1

I found the problem:

The templates were not at all responsible.

I am using the JCH Optimize plugin. In the Basic Options tab, there is a Use url rewrite parameter. That was the problem. When I switched it to off, the conflict stopped.

For some reason, it does not work well with the directives inside my .htaccess file.
