on joomla 3.3.6 some weird thing happened: the url's are not being rewritten to SEF. Everything is enabled and all. The weird thing is that the menus on site are rewriting their URL's and link to SEF as usual.
I have updated to J3.4.1 (latest) to no avail..
Checked htaccess - all good, and even changed with another from working site.
What else can I do?
