If you can downgrade the MySQl to 5.7 please do that, the MySQL 8 is not supported yet.

wpForo will support MySQL 8 with the next version. We'll release the next version by the end of this month.

any idea when this would be fixed?

Ok, thank you for the information. We've found the issue, and we're fixing it now. I'll provide some solution soon.

my developer was looking into this and this is what he said:

my finding is that there is a query string in wpforo that gets the forum child that's probably not workin in mysql newer version

 

the query string is inside the get_childs function under class-forums.php

 

I tried a new query approach and it worked.. but I reverted the changes at the moment because wpforo team you contacted might still be working on it

on my localhost, I installed two versions of mysql..
one is the latest which is 8.0.22 which HP is also using
the other is 5.7.24.I run the same query using the two versions.. the older version works and the new one doesn't

this is from 8.0.22 version of MySQL- https://www.screencast.com/t/3sf6WnaX2

this is from an older version of MySQL - https://www.screencast.com/t/EutU6I7WbuRE

so not sure if any of this is related?

Just something i saw... i have the forum installed on 2 websites... they have slightly different mysql versions.

it works fine on version 8.0.21

but the server healthypages is on is 8.0.22

Please contact us via supportgvectors.com email address and refer to this topic.

its not cache as all other changes on the website are displaying when made

anyway, i disabled the object cache and cleared all caches again, and its still not working?

Something really strange is going on in your website. I think the problem is your cache solutions. Could you please purge all kind of caches and the server side nginx cache as well?

Also, in any case, please disable wpForo Object Cache in Dashboard > Forums > Settings > Features Tab.

i deleted the cache and then added 2 dummy forums under therapy forums, they did not appear on the front end. The site is on gridpane and uses serverside nginx cache, which i have cleared also many times
