Are you on a local or on a production install ?
Are you connected as site admin when the error occurs ?
hi there, no, not a localhost, it’s a finished live site 🙂
Yes, I’m connected as an admin…
Do you have error message when wp-debug is activated ?
Generally a 403 error is related to a lack of ressource on server side. Ask your host if you find nothing.
Hm, I enabled he debug mode and nothing showed up… thank you anyways for your answer!
A 403 response usually indicates the resource you requested is forbidden. Something like this could happen for various reasons. The first place to start is your .htaccess file; check there’s nothing crazy going on inside that. A basic WP .htaccess file with no customisation should look like this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
