Sorry for the long heading. After updating to WordPress 5.3.1 the 'add media' button from new posts doesnt work unless I deactivate the all-in-one event calendar from Timely (I tried all my plugins to find out). But I need this calendar for my site. Has anyone had this before and does anyone have any suggestions?
(by the way the upgrade has also stopped the link button from working in new posts too, but nothing seemed to work to fix this, even deactivating all plugins, any tips on this would be great).
Looking forward to your help!
