Hi @611shabnam
Thank you for caring.
I am facing another issue – also a warning when trying to edit files of image in backend.
Actually, after latest updating, whenever images uploaded by users, the name of an image would always be added with an extention of 8 digits, a combination of letters and numbers after a hyphen, for example: the orginal name is “zkclxljyhhqt.jpeg”, then it becomes “zkclxljyhhqt-2cef593c.jpeg”.
It won’t happen so, as an editor upload pictures by WP default uploading method, other than by “User Frontend” plugin.
I don’t know PHP coding. Yet the following warnings when trying to edit media files uploaded through User Frontend displayed like this:
Fatal error: Uncaught Error: Call to a member function exists() on bool in …/wp-admin/includes/media.php:3295 Stack trace: #0 …/wp-includes/class-wp-hook.php(287): attachment_submitbox_metadata(Object(WP_Post)) #1 …/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(”, Array) #2 …/wp-includes/plugin.php(484): WP_Hook->do_action(Array) #3 …/wp-admin/includes/meta-boxes.php(430): do_action(‘attachment_subm…’, Object(WP_Post)) #4 …/wp-admin/includes/template.php(1389): attachment_submit_meta_box(Object(WP_Post), Array) #5 …/wp-admin/edit-form-advanced.php(681): do_meta_boxes(Object(WP_Screen), ‘side’, Object(WP_Post)) #6 …/wp-admin/post.php(206): require(‘/www/wwwroot/ww…’) #7 {main} thrown in …/wp-admin/includes/media.php on line 3295
Looking forward to your advice with my sincere appreciation.
Best wishes,
