error after account creation

[Tempest]

So when new members join the forum they are getting this error and they can't access any of the forum. Once they activate their account  the error goes away. Just wondering if anyone knows how to fix this? thank you!

Your forum is configured to require user being logged in so if they're not registered users they'll have the error message (bottom part of your screenshot).

As for the PHP warning in the top part of the screenshot, I want to ask which MyBB version is your forum on?

I did have that setting on but recently disabled that when we opened. Is there something else I can do to change that?
We are on version 1.8.5

just a quick bump, thanks everyone!

What cache handler does the forum use?

Can you show the result of this SQL query?

SELECT length(cache) FROM mybb_datacache WHERE title = 'usergroups'

If you are still using 1.8.5, you should also upgrade to the latest version.

PHP 5.6.38?
Was EOL almost 2 years ago.
