Hi,
I upgraded from 2.8.0 to 2.8.1 and it stalled at clearing cache. After a long while, I shut down my browser.
Mautic started giving an error so I manually deleted the cache (deleted everything inside /cache)
I even restarted Litespeed to clear opcache.
It appeared to start working OK except when I create a campaign it gives a (graceful) error 500. The campaign is in fact created and appears on the list but if i click on it, it gives again an error 500. Strangely, I can edit it, just not see the details such as campaign members etc.
I have tried with a number of very basic campaigns and it always happens.
I have deleted the cache, downgraded from php7 to 5.6 and cleared opcache, all several times.
Can I downgrade to 2.8.0?

I see what happened is the upgrade process was halted because it hit the maximum PHP execution limit. I would suppose that left a very unhealthy install, lucky it even works.
Regardless, is there a way to force a reinstall or downgrade?
Many thanks

Personally, I’d restore from backup and start over.
