I installed Jom Classifieds on my website, but when I tried to make some basic changes at the "General configuration" tab I got this message:
Not Acceptable
An appropriate representation of the requested resource /administrator/index.php could not be found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
I tried with many different browsers, and different computers, just to be sure. Everything else on the website is working with no problem.
Can you please help me out?
Thank you.
