EX0 error on forum guest access

[thefeeder]

All my guest users are experiencing an EX0 error when they attempt to access any forum page. Any idea why this might be happening? 

Example: https://www.letsgosharks.com/forums/  (they should be seeing my forum home page which displays an index of my forums):

 

I'm running v 4.4.9

There was also an alert (that I suppressed and won't be able to see until tomorrow) which mentioned there were some tasks that were not running because they are run when users visit my site, and this was the case because I had low user count (my forums are seasonal). Not sure if this is contributing to this issue.

This is what was highlighted by the tasks issue:

 

When I click on the View Tasks link I see that everything was "last run" today with the exception of a few that show "Not currently needed."

As mentioned in one of your other tickets, the first thing to do here is to upgrade to the latest release of the platform. At the moment you are 34 releases behind, including multiple which are security releases

That is a general error and doesn't tell us much. Can you check the Systems Log page and see if there are any errors logged in there pertaining to this? Also, what was the latest change done to the forum prior to this happening?

If I were you, I would upgrade the forum a.s.a.p. as advised above.

Yeah, I need to find a vendor to help with that. I'm afraid of blowing up the forum if I try to do it myself. 

Checking on syslogs...

OK I see a bunch of these in the syslogs:

If you need help with the upgrade have a look at the Providers Directory, specifically the profiles with the Upgrade Services badge: https://invisioncommunity.com/third-party/providers-directory/ 🙃

I upgraded to v4.4.10 a couple of years ago

That is a bug in that version that manifests as a fatal error in later versions of PHP. The only fix is to upgrade, I'm afraid.

Thanks Ryan. Appreciate the insight.
