Justin Tadlock 3 years ago Nothing in the error you posted points toward the Admin Access plugin or really tells me much. It being a JS issue hints at it possibly being related to Ajax, but the issue you described doesn’t sound like an Ajax issue. On line 29 of members-admin-access/app/functions-admin.php, you might try changing this line: if ( ! current_user_has_access() ) To this: if ( ! current_user_has_access() && ! wp_doing_ajax() ) That would rule out an Ajax issue. If the EDD add-on is attempting to access anything via the admin (Ajax requests are sent through the admin), it’ll get blocked with this plugin for users who don’t have access. Other than the toolbar, that bit of code above is literally the only thing in the plugin that touches anything in the “global” WP space that could possibly mess with other plugins. I can’t think of any reason their plugin’s script was being loaded twice (due to any other plugin) unless they were doing something non-standard. Admin Access loads no scripts of its own either. I do want to note that, per Theme Hybrid’s terms, I cannot guarantee that plugins won’t conflict with third-party software. But, I’ll try to help the best I can.
