HTTP Error 500 at main forum page after Discourse upgrade

Hello,

We have upgraded our forum today to the latest version, but got HTTP error 500 at the root page. The following message appears in the production.log file inside the container when the root page opens with error 500:

I have tried to rebuild the container, but the problem not disappeared. The admin page works without any problems. What should we do to repair the forum?

We’re aware and looking into it! Looks like it might be a bugged commit causing the issue.

We’ve identified a commit on Solved that may have been causing a conflict.

It’s been reverted so please try rebuilding and let us know if you continue to have problems.
