Array to string conversion

[swinggraphics]

The warning is generated on every admin page. I added the backtrace output.

Hello @swinggraphics,
sorry to hear about your problem. As we checked, it seems working on our end. There might be a conflict with another plugin or theme. Let's do a conflict test to be confirmed.

Please deactivate all plugins except the WP User Frontend and WP User Frontend Pro.
Use a default theme such as twenty-twenty-three.
Clear your site cache as well as the browser cache. Then try again.
If you're still getting that problem, please contact our support so that we can check it in every possible way.

Yes, this appears on every admin page with only Twenty Twenty-Three, WP User Frontend and WP User Frontend Pro active.

Considering the issue resolved with our proposed solution. Closing it now. Feel free to reopen if needed.

Appreciate your collaboration!

In case anyone else runs into this, my solution was to stop using WP User Frontend and WP User Frontend Pro.
