XF 2.1 Upgrade error

[Rhody]

I am moving an existing 2.1.3 to a new server this week, and just put a test backup on the new server and tried the in place upgrade from the admin console.

It seemed to be running fine, until I tried to upgrade.

This was the result, and it seems stuck in "the forum is being upgraded, check back later" mode...

I did it from within admin panel, and also tried /install folder button. PHP is 7.4 on a litespeed server

Any ideas? corrupted database? permissions?
Thanks

XF 2.1.3 is not compatible with PHP 7.4.

You need to upgrade to at least XF 2.1.4 I think though at this point we'd just strongly recommend going all the way up to XF 2.1.7.

You'll need to do this upgrade prior to the move to the server with PHP 7.4 or downgrade PHP on the new server first.

Ah thank you Chris! Now it makes sense.

I temporarily changed it to PHP 7.3.15 and it worked well.

Thanks again
