I have some reseller hosting and I am running Drupal 7 sites on several different accounts there.

I recently noticed a problem when updating one of them. It happens when I am editing content or changing admin settings.

• I go to an admin page - e.g. my.site/admin/people/permissions.

• I make a change and hit "Save".

• The page submits and reloads. The address bar still says my.site/admin/people/permissions, but the page content is:

  Page not found
   The requested page "/admin/people/permissions" could not be found.

I tried changing .htaccess files, disabling modules, etc, but nothing worked. In the end I did the following:

• Created a new hosting account on my reseller hosting
• Installed a fresh copy of drupal-7.58
• Created a new database

When I repeated the actions above, I got the same results, except this time the error message was:

Forbidden
You don't have permission to access /drupal-7.58/admin/people/permissions on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

I then checked another account on the same reseller hosting. It's running drupal-7.54 but also shows Page not found.

I didn't have the problem a few weeks ago, so I am wondering if my hosting company has changed something in Apache which is causing this problem (really clutching at straws here).

Versions I am running:

• Apache Version 2.2.32
• PHP Version 5.6.30
• MySQL Version 10.0.34-MariaDB

Can anyone help? Has anyone ever seen anything similar?

TIA
