Title: Invalid argument supplied for foreach() errors Last modified: August 30, 2016 --- # Invalid argument supplied for foreach() errors * Resolved [Peter Hardy-vanDoorn](https://wordpress.org/support/users/petervandoorn/) * (@petervandoorn) * [10 years, 5 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/) * Since updating to the latest version I’m seeing this error, but only on the backend: * `Warning: Invalid argument supplied for foreach() in /.../wp-content/plugins/ advanced-access-manager/Application/Backend/Extension.php on line 87` * and also on line 169 when viewing /admin.php?page=aam * [https://wordpress.org/plugins/advanced-access-manager/](https://wordpress.org/plugins/advanced-access-manager/) Viewing 9 replies - 1 through 9 (of 9 total) * [vasyl_m](https://wordpress.org/support/users/vasyl_m/) * (@vasyl_m) * [10 years, 5 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6806801) * Hi **Peter**, * Thank you for your feedback. * That is kind of a weird warning, considering the fact that on the line 87 there is no foreach loop. * Please try to install AAM Utilities extension and clear all settings. This might help you to avoid the second warning. * Keep us updated. Regards, Vasyl * Thread Starter [Peter Hardy-vanDoorn](https://wordpress.org/support/users/petervandoorn/) * (@petervandoorn) * [10 years, 5 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6806804) * I had thought to try the Utilities extension, but unfortunately the 2 errors completely break all AAM functionality, so the Download button doesn’t work! * I have also already tried deleting the plugin files and reinstalling via FTP, but I don’t really want to try deleting it through WP as I don’t really want to delete the extensive user role settings! * [vasyl_m](https://wordpress.org/support/users/vasyl_m/) * (@vasyl_m) * [10 years, 5 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6806851) * Hi **Peter**, * As a quick fix, you might try to go to database and remove the option **aam-extension- list** in your **wp_options** table. * The permanent fix is coming with our new release AAM 3.0.4 in couple days. * Thank you for your feedback and let me know if this works for you.

I’m running 3.0.9 and get the same warning: `Warning: Invalid argument supplied for foreach() in ../wp-content/plugins/advanced-access- manager/Application/Backend/Manager.php on line 87`. * `Warning: Invalid argument supplied for foreach() in ../wp-content/plugins/advanced- access-manager/Application/Backend/Extension.php on line 180` * When visiting the AAM page in the admin I also get three alert pop-ups, all with the same warning: `DataTables warning: table id=role-list - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1` * Opening the extension tab, there one more warning: `Warning: Invalid argument supplied for foreach() in ../wp-content/plugins/advanced-access-manager/Application/ Core/Repository.php on line 224` * [vasyl_m](https://wordpress.org/support/users/vasyl_m/) * (@vasyl_m) * [10 years, 3 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6807069) * Hi **Studiobovenkamer**, * Please install [WP Error Fix](https://wordpress.org/plugins/wp-error-fix/) plugin so we can catch all your errors and provide fixes until the next AAM release is ready to go. * Thank you, Vasyl * [webdigit](https://wordpress.org/support/users/webdigit/) * (@webdigit) * [10 years, 3 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6807075) * Hi Same issue :/ It seems to break media manager too :s * Thanks a lot for the futur fix 🙂 * JC * [Dawid_W](https://wordpress.org/support/users/dawid_w/) * (@dawid_w) * [10 years, 3 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6807076) * Hi All. Had the same problem but solved. (Backup files before editing) * For error: 1) Warning: Invalid argument supplied for foreach() in /…/wp-content/ plugins/advanced-access-manager/Application/Backend/Manager.php on line 87 * **Solution**: In line 87 change “foreach($list as $extension)” to “foreach(( array)$list as $extension)” * 2) Warning: Invalid argument supplied for foreach() in /…/wp-content/plugins/ advanced-access-manager/Application/Core/Repository.php on line 224 * **Solution**: In line 224 change “foreach ($list as $row)” to “foreach ((array) $list as $row)” * 3) Warning: Invalid argument supplied for foreach() in /…/wp-content/plugins/ advanced-access-manager/Application/Backend/Extension.php on line 180 * **Solution**: In line 180 change “foreach($list as $extension)” to “foreach(( array)$list as $extension)” * That works for me.

We were overloaded here with some other stuff. This issue will be resolved today. I’ll personally will make sure that it will. * Meantime please give a try to [WP Error Fix](https://wordpress.org/plugins/wp-error-fix/) plugin. This will allow us to get notified about PHP errors related to AAM. * Thank you, Vasyl * [geleto001](https://wordpress.org/support/users/geleto001/) * (@geleto001) * [9 years, 10 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6807107) * Hi, * I have the same problem . After an updated I’ve received the same message :Warning: Invalid argument supplied for foreach() in /home3/geleto001/public_html/wp-content/ plugins/post-grid/grid-items/variables.php on line 87 * It seems that the discussion is but the problem appears again .

I’ve wanted to try the Dawid_W’s solution but didn’t found the “foreach($list as $extension)” , so I can’t change it . * Thanks in advance , Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘Invalid argument supplied for foreach() errors’ is closed to new replies. * ![](https://ps.w.org/advanced-access-manager/assets/icon-256x256.png?rev=3447421) * [Advanced Access Manager – Access Governance for WordPress](https://wordpress.org/plugins/advanced-access-manager/) * [Support Threads](https://wordpress.org/support/plugin/advanced-access-manager/) * [Active Topics](https://wordpress.org/support/plugin/advanced-access-manager/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/advanced-access-manager/unresolved/) * [Reviews](https://wordpress.org/support/plugin/advanced-access-manager/reviews/) * 9 replies * 6 participants * Last reply from: [geleto001](https://wordpress.org/support/users/geleto001/) * Last activity: [9 years, 10 months ago](https://wordpress.org/support/topic/invalid-argument-supplied-for-foreach-errors/#post-6807107) * Status: resolved
