XF 1.1 XenForo 1.1.4 Upgrade Fails!

[Quiver]

XenForo 1.1.4 upgrade is repeatedly failing for Admins Forum.
Error: "Line 18: Template Syntax Error". It's locked in upgrade.
I cannot use the forum unless I upgrade. But I cannot upgrade.
I didn't take a backup either, which is my biggest ever mistake!
I suppose I wasn't expecting something to go wrong. SILLY ME!
Could someone please offer advise? If that's even possible for this.
Because my biggest fear here is: Start all over again. No thanks.

Didn't you get the same error in January?

Very similar. But that was fixed by clearing my browser cache.
I am very unhappy to say that that trick is not working now.

In which step does this happen?

It gets as far as rebuilding Admin Templates (importing).

It's possible you had a corrupted download/upload. Download the 1.1.4 update from XF and upload the files to your server, then attempt the upgrade again.

That appears to have been the issue. All working now, thanks.
