XF 2.1 Upgrade Issue

[Ranger375]

I was trying to update to v2.1.6 Patch 1, but in the upgrade process it ends with the below error. How can I fix this? Basically, my forum/admin panel are stuck on the site is being upgraded" message and I can't seem to do anything.

Did you do the upgrade via the ACP or manually upload the files? I would try it by uploading the files manually.

This would be the result of server limitations. Are you on shared hosting? If so, this is something to work out with your host.

Nah I have a dedicated server and have only done manual upgrades. I reran the installation process a third time and it worked. I’ve never had an issue previously.
