I cant soft delete any thread or post (In any forum). I am Super Admin, I have all the permisions.
Its dont show any error in console or network, the page be refreshed but nothing happend.
I am using v2.2.7 Patch 1, on the previus version it worked. I only can use hard delete.
I had the same problem with "like_users" and +800k posts. (Step18 in 2010010-210a.php)
I fixed it, creating the column "like_users" from phpMyAdmin ;)
ALTER TABLE `xf_post` ADD `like_users` BLOB NOT NULL AFTER `embed_metadata`;
