mlollar Kindly check as admin details arent to be seen now in order to access the respective page.
Can you add the details in format outlined below in edit fields :
Site admin account
Admin panel username/password
Ftp info (host, user, pass)
Ftp hostname, username, password
I've tried different template styles for the page and doesn't seem to matter. Clicking on the tabs does nothing.
If the issue persists with assigning default Joomla template, it is unlikely to be an apparent issue specifically with T3 framework however appears to be an issue with JS loading css selectors for the specific extension which are conflicting. You may also contact the developer of specific extension for the same if the issue is also apparently seen with default Joomla template as mentioned by you
