Three steps to resolve Joomla problem with Search Engine Friendly URLs
Sometimes when we set the option “Search Engine Friendly URLs” in Joomla SEO Settings, it makes several broken links (error 404) and site appearance becomes inappropriate. To resolve this problem I found the followings steps useful:
۱. If your web server is Apache, rename htaccess.txt file in the root of Joomla installation to .htaccess
۲. In Global configuration under “SEO Settings” set the option “Use Apache mod_rewrite” to “yes”. Hopefully the problem will be solved, but if not do the third step.
۳. Change the contents of the .htaccess file to the following and save it. If you still experience the problem I can’t further help you!

# The line just below this section: ‘Options +FollowSymLinks’ may cause problems

may already

out (add # to

If they work,
