Hi,

Thanks a lot for pointing to this bug. It’s a typo. Quick fix: open post-edit-access-role.php file for editing and replace plus ‘+’ character with this the dot: ‘.’
Correct version of line #72:

return array('result'=>'success', 'message'=>'Posts edit permissions for role:'. $role_id, 'html'=>$html);

I included this fix to the next release.

What i did was, switch to php 7.4 instead of php 8.0.

We were getting permission rejections when we updated to 8.0.

People would log in and it would push them to the ‘not allowed’ page wihtout an error message. Had to roll back too.

@TrinWEb,
Can you give more details with problem under PHP 8.0 – error messages at the server log file after switching WordPress to debug mode, browser JavaScript Developer Tools Consol and/or Network panel error messages?
