 * Hi,
    I was trying out the free version of your plugin but was finding that when
   it was enabled, I was getting an error in my wp-admin dashboard widgets. The 
   critical error message was appearing just under the text inside the “at a glance”
   dashboard widget and in the console there was a 500 error for wp-admin/index.
   php.
 * After going to a staging site and disabling and reenabling a bunch of things,
   I found that the error is occuring when I have BOTH Glossary and USP Pro enabled.
   If I disable one or the other the error clears up.
 * When I turn on debug, I see the following error message inside the “at a glance”
   widget:
 *     ```
       Fatal error: Uncaught TypeError: Extended_Taxonomy_Admin::glance_items(): Argument #1 ($items) must be of type array, null given, called in /var/www/html/site/public_html/wp-includes/class-wp-hook.php on line 307 and defined in /var/www/html/site/public_html/wp-content/plugins/glossary-by-codeat/vendor/johnbillion/extended-cpts/src/class-extended-taxonomy-admin.php:545 Stack trace: #0 /var/www/html/site/public_html/wp-includes/class-wp-hook.php(307): Extended_Taxonomy_Admin->glance_items(NULL) #1 /var/www/html/site/public_html/wp-includes/plugin.php(191): WP_Hook->apply_filters(NULL, Array) #2 /var/www/html/site/public_html/wp-admin/includes/dashboard.php(356): apply_filters('dashboard_glanc...', Array) #3 /var/www/html/site/public_html/wp-admin/includes/template.php(1401): wp_dashboard_right_now('', Array) #4 /var/www/html/site/public_html/wp-admin/includes/dashboard.php(265): do_meta_boxes(Object(WP_Screen), 'normal', '') #5 /var/www/html/site/public_html/wp-admin/index.php(203): wp_dashboard() #6 {main} thrown in /var/www/html/site/public_html/wp-content/plugins/glossary-by-codeat/vendor/johnbillion/extended-cpts/src/class-extended-taxonomy-admin.php on line 545
       There has been a critical error on this website. Please check your site admin email inbox for instructions.
       ```
   
 * I have tried, on the staging site, resetting both plugins back to their original
   settings. And I’ve tried switching to a default theme. But there isn’t any change.
 * I am considering purchasing the pro version if I can get this working, but don’t
   want to stop using the other plugin. Would there be anything within the pro version
   that would solve this?
 * Thanks

 * Well, at least for now I disabled USP and added a different form, so the error
   is not occurring.

 * Hi Cheryl,
    the error happens because USP pro is not managing that dashboard 
   widget in the right way and our plugin intercept that error.
