Any help with it ?

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.

[TrinWeb]

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?

I’m also getting the “Ajax failure” error when when clicking the “Other Roles” button (after enabling the “Activate Other Roles Access Module”, so I am not able to configure the “Other Roles” checkboxes. I’ve tried in two browsers.

Can you take a look and let me know what could be wrong?

[Vladimir]

Try in Developer Tools in Google Chrome (F12), select Network tab, click “Other Roles” button at URE, select admin-ajax.php row at the bottom and look at the Response tab for the error message if available.

[Vladimir]

Or send admin credentials to support [at-sign] role-editor.com in order I can look on the issue myself.

[dshank]

The error in the console is 500, type “xhr”,

“Initiator”:

/wp-admin/load-scripts.php?c=0&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils,wp-polyfill-inert,regenerator-runtime,wp-polyfill,wp-hooks&ver=6.2.2

[Vladimir]

It seems as jQuery is not loaded at all, but once you see error message after click on the “Other roles” button, event was assigned to the button via jQuery.

Is it possible to look at the stage copy of your site to search a reason?

[dshank]

Yes, how can i send you access details?

[Vladimir]

Send to support [at-sign] role-editor.com

@dshank, You have older unsupported version of URE Pro – 4.51.2, which had the bug, caused syntax error:

[07-Aug-2023 04:22:24 UTC] PHP Fatal error: Uncaught TypeError: Unsupported operand types: string + string in /public_html/wp-content/plugins/user-role-editor-pro/pro/includes/classes/other-roles.php:258

It was found at have fixed at version 4.57.

I fixed this bug at your stage server, but recommend to update to the latest version of URE Pro, if you plan to use it.

[dshank]

Thank you for the follow up. I have just purchased a lifetime license so that I can use the updated versions.
