PROBLEM Forbidden You don't have permission to access this resource

Hi Eric,

Did you check if your index.php or .htaccess files are for some reason corrupted ?
Try to install a new 3.3.16 setup somewhere in a subdomain and see how that works.
======================================

Looks like your website is hosted on argeweb.nl
Their online support does not bring up much:
https://www.argeweb.nl/zoeken/security
======================================

Try the following:

Go to your argeweb CPanel and look for the mod_sequrity setting
Turn off mod_sequrity for your website and check if the error
disappears.

Here is an example where to find mod_sequrity inside CPanel

Of course this CPanel might look different but it gives you an idea where to look
in your argeweb CPanel
======================================

If the above doesn't work you can try to put these lines of code in your .htaccess file


<IfModule mod_security.c>

SecFilterEngine Off

SecFilterScanPOST Off

</IfModule>


Check if that makes the error go away
======================================

If the error still does not go away you have to contact your hosting support
and let them check the Apache error log for your website. You mentioned that
they do not want to change their firewall rules, ok that is understandable,
but they can at least check the Apache error log for your website and inform
you what exactly is the reason for the error.

Just let us know if any of the above works out.


If all of the above does not work you can try to use another hosting
