I can't access administrator's page, it returns 404 error not found. Although when I rename
htaccess.txt, admin page works , but whole site returns 404 error not found. When I rename it back to
.htaccess, website pages work, but not the admin page.
I am using joomla 3 and I am using an extra login layer (from a plugin, but can't remember its name) for the joomla administration panel. Does anyone know what is causing this?
