When I activate a theme that I made, after any save or submit that refreshes the page on
wp-admin I get a blank screen, If I go back and refresh the page the settings are saved.
If I close the page in this blank state, I can't reopen
wp-admin and get blank page on any wp-admin subfolder
I installed my theme on a fresh WP site and the problem reoccured, however it only happens when I work on a mac (with MAMP), I have WP with the same theme on a PC (with XAMPP) and it doesn't happen there.(restarting MAMP or the mac didn't help)
This problem does not seem to effect the WP site, only the admin.
Any ideas what that might be?
