Thanks for your help everyone :) 

Ok, thank you for letting us know. We'll add some changes to prevent such errors. This is not a core issue, but this can be prevented as well.

• PHP Warning: Trying to access array offset on value of type null in /home/percysgr/public_html/wp-content/plugins/wpforo/modules/reactions/classes/Template.php on line 82
• PHP Warning: Undefined array key 1 in /home/percysgr/public_html/wp-content/plugins/wpforo/modules/reactions/classes/Template.php on line 82

This is what is online 82:

	wpforo_member_link( WPF()->member->get_member( $l_usernames ), '', 30, '', false, $l_usernames )

But most likely i overlooked it. I have deleted the duplicate section and all that now so hopefully this could be the end to the problem. 

I will let you know if i get the out of memory warning again over the next few days or not. Thanks for your help lads 

If the parent of Growing in Soil is Grow Guides, you should change the parentid of the Growing in Soil forum to 3, because the forumid of Grow Guides is 3. So just change the parentid from 172 to 3, do not change the forumid, you should only change the parentid.

The Parent forum for Growing in Soil is Grow Guides, and the parent of grow guides is cannabis growers forum.....

Do I just change the number of the parent forum in this box, so it is the same as "grow guides">

Here is the first issue I found. The forum with 172 ID has the same parent ID 172. So it loops through parent-child unlimitedly:

https://wpforo.com/wp-content/uploads/2024/01/Screenshot-2024-01-09-at-10.29.01.png

You should change the parentid of the forumid 172 to something else, if it's a parent category, the parentid should be 0. If it's a child of a parent category then the parentid should be the forumid of the parent category.

Once you changed it in the database, go to wpForo > Overview admin page, click the follwoing buttons:

3. again
4. Go to wpForo > Forums admin page, make sure the forum with 172 ID is in the correct place and click button

And check the wpforo_forums table again, make sure the parentid of the 172 forum is correct.

There could be data issue as well. So the child forum cannot find the parent forum, and it loops the recursive function unlimitedly, filling the memory.

This sounds very much like it could be the cause of some of the issues. Ill run a back up and send the files over when it is done. Thanks for your help 

Also, please export wp_wpforo_forums table, zip it and attach it here if possible. There could be data issue as well. So the child forum cannot find the parent forum, and it loops the recursive function unlimitedly, filling the memory. This kind of issues arises when you do some database manipulation, or the database table become unhealthy.
