[Pushed] foreach errors with count()

[Lunorian]

Occasionally MyBB is returning the following error message to users.
   
So far this has only happened with PHP 7.2, switched to PHP 7.3 in hopes of resolving the issue. It only happens sometimes so it's difficult to reproduce the issue. Has anyone else experienced this?

EDIT: This actually shows up everytime I view the new thread page, also rebuilding the cache seems to make it go away for a while. I use memcached.

It seems to be as a compatibility issue with php 7.3.x

Is there a GitHub issue tracking this bug? When should I expect a fix?

[Eldenroot]

I dont think so, feel free to open a new ticket and push a fix via PR.

Hi Lunorian, are you still experiencing this issue recently? If the answer is yes, please go to AdminCP > Tools & Maintenance > Cache Manger open and copy following caches' contents, when this warning appears:

• smilies
  
• moderators
  

If you read blank page or no cache content displayed, could you please run following SQL queries:

SELECT `title`, LENGTH(`cache`) AS cache_length FROM mybb_datacache WHERE `title` IN ('smilies', 'moderators');

The SQL query results are safe to post back to this thread. If you mind the contents of above caches, you could post them in the Private Inquiries section or send them to me via PM. Thanks.

P.S. a PM is also sent to you, sorry to disturb.
