On a live server, whenever I attempt to save an edit to a metafield of an image (file template), I am logged out of the panel. The save is not completed.
I am also logged out when trying to delete an image.
I have tried deleting all sessions, disabling cache of browser, adding the below to .htaccess
<IfModule mod_expires.c> ExpiresActive off </IfModule>
I am using v 3.5 of Kirby & running php 7.4.
Any help with this would be great.
