Just installed Companion Revision Manager – Revision Control on WP 5.0.3 and got into trouble.
First issue, in settings whenever I click Save in plugin settings it shows error:
Warning: Cannot modify header information – headers already sent by (output started at wp-includes/formatting.php:5101) in public_html/wp-content/plugins/companion-revision-manager/companion-revision-manger.php on line 75
But that is not real issue. The real problem is after i clicked button to delete existing revisions, it deleted them and totally disabled revisions option in WordPress (no i did not check option to disable).
Disable means, revisions are still created but no options to mange them is displayed. Revision manager is removed from post editor and there is no option to enable it again. Site behaves like that option does not exist. Even option to show revisions in Screen options is removed.
Disabling plugin did not help.
I found out that plugin changed wp-config.php and added define(‘WP_POST_REVISIONS’, 1 ); I tried to change value and even delete this setting but nothing helped.
How can i revert site functionality to be as default and before this plugin is installed?
