Errors in multisite
We have the admin columns pro plugin and activated it on the multisite network we have. When we go to the admin columns settings page, all we see are these errors.
Warning: Invalid argument supplied for foreach() in /wp-content/plugins/admin-columns-pro/base/classes/settings.php on line 495
Warning: Invalid argument supplied for foreach() in /wp-content/plugins/admin-columns-pro/base/classes/settings.php on line 495

Warning: Invalid argument supplied for foreach() in /wp-content/plugins/admin-columns-pro/base/classes/settings.php on line 655
Consequently, we can’t edit the columns in the admin. Please help.
We’ve been in touch with Lance and the issue has been solved. The errors occurred due to a fault in the WordPress setup, which was solved by reinstalling WordPress. Marking topic as resolved!
