This problem only seems to affect admin users.
Only affects some posts, not all posts.
A admin user will create a new topic in a category. The topic will be posted to the forum successfully. There will be no warnings/notification on the initial topic that it will be auto closed. After about 5-10 mins, The topic will show that it will be auto close after 60 mins.
I am sure that I did not set the auto close flag for this topic.
I am sure that the category does not have the “auto close after x” flag set.
I am sure that none of my other admins set this flag either.
This category seems to have all the posts that are auto closing.
On creation of a new topic this “zzz !!! Don’t use this !!! old categorized” category is not select-able. Even for admins.
I was able to edit this category after enabling uncategorized topics in the admin settings. The auto close setting was enabled on the settings for this category.
Thank you once again, this has been bugging me for a few weeks now.
