Hi,
I updated WordPress to 5.5.3. Following issues have occured:
1.) The media library is now completely empty and no item is shown at all. When I upload an image it disappears. So I have no access to the images via WP backend.
2.) In the plugin section I can’t choose multiple plugins anymore, so now I have to click on each plugin for activation or deactivation.
3.) When activating “debug true” in the wp-config the backend shows several warnings “Cannot modify header information” in the functions.php, misc.php and admin-header.php
4.) Another warning when activating “debug true” in the wp-config: The add_submenu_page header is loaded incorrectly. The seventh parameter that is delivered to add_submenu_page() should be an int, which should represent a position of the menu.
Could you please fix these bugs and release an update of the theme?
Thank you very much!
