After a WordPress update I got the following problems:
- In /wp-admin/edit.php?post_type=page — clicking ‘quick edit’ link made the page disapear from the list
- Clicking the permalink ‘edit’ button didn’t work (you couldn’t edit the permalink)
- It was impossible to set the pages visability settings, set to draft etc.
I tried:
– All plugins deactivated
– Delete and replace wp_admin and wp_includes folders
– added define(‘CONCATENATE_SCRIPTS’, false ); to the wp_config
It turned out to be a javascript colour picker in a custom admin panel in the theme did not like the upgrade. Commented out the JS and Bob‘s yer uncle, it worked.
