Error: Forbidden You don’t have permission to access this resource.

This error is usually due to some permissions problem. Did you check the file permissions on the server? To debug this problem see the following: https://developer.www.ads-software.com/advanced-administration/debug/debug-wordpress/

This should provide more information on what is causing the problem.

Thank you for your quick response. I’m not sure if it helps me with debugging, because 5 different websites are affected, which are on different servers (but all on Strato.de). One site has an old WordPress version and an old EM version, this site also gives the error. However, two weeks ago everything was still working. What also works is searching the WordPress posts in backend. Strangely, only the Events Manager is affected.

Maybe Strato.de changed something on their servers? The wordpress debugging will let you see any php errors.

I don’t know if Strato has changed anything, maybe I’ll ask tomorrow. I’ll have to take a look at the debugging, it looks complicated at first glance…

You just need to edit the wp-config.php file and add the following lines:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_DISPLAY', true);
define( 'WP_DEBUG_LOG', true );

The errors should show on ths display as well as in the wp-content/debug.log file

Thank you!

I’ll try that and get back to you.

I edited the config.php. Unfortunately there is no PHP error. The only one error is in the JavaScript console of my browser:

Failed to load resource: the server responded with a status of 403 () https://www.*****.net/lab/extra/wp-admin/edit.php?s=test&post_status=all&post_type=event&_wpnonce=26de3a4377&_wp_http_referer=%2Flab%2Fextra%2Fwp-admin%2Fedit.php%3Fpost_type %3Devent&action=-1&m=0&scope=future&event-categories=0&paged=1&action2=-1

I also changed the theme, but it didn’t help.

Do you have a WP Multisite installation?

Try rolling back the Events Manager to an earlier version to see if the problem is related to a plugin change (you can use the WP Rollback plugin to do this).

Here are some other suggestions for dealing with 403 errors: https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-403-forbidden-error-in-wordpress/

No, they are all individual installations.

And one site has an older version of EM, but it has the same error. I also found the help page you mentioned ?? and just worked through it, unfortunately no success either.

Did you get any help from Strato on this error?

I spoke to Strato on the phone. They have not made any changes to the servers. And the employee said no one else had called about this error either.

To test it, I have now installed WordPress in a subfolder, with a new database and no additional plugins or data. Then just added the Events Manager plugin. The error appears here too.

?I also just installed WordPress in a subfolder, with a new database and no additional plugins or data. Then just added the Events Manager plugin and I don’t see the error. Must be some setting on the Strato server that is causing this error.

Wow thank you very much! Did you search for an event in the backend? Or tried to view all events instead of just future ones? The error only occurs in the backend.

I created one event in the backend and then I was able to view all events in the backend (which showed the event).
