Database Import result 403 Forbidden

I changed the Max_Upload_Size to 50MB, and the web keeps sending data and don't show upload progress. It ends up with this notice:

Forbidden

You don't have permission to access /phpMyAdmin/import.php on this server.

Even though this thread is a little old, I feel that I should point out what the actual issue is for the others who are getting such issue.

This is likely to do with mod_security2. You'll need to go to the control panel, security, mod_security, find the rule ID triggered in its log, and add it to the disabled rules file (there should be a hyperlink to it there).

This is what I currently use (and pMA is having no issues for me ever since):
