[Forum] Error message received during upgrades

[Mark.B]

Now, I should say this error was not particularly worrying. It has been coming up during the last two or three upgrades I have done on my site. But all you is click ok, refresh, and carry on. So it's not a "problem" I need help with as such, my upgrade today has completed, but these errors still occur and I can't explain them. I'm curious.

I've done all the usual, checked all the files are uploaded etc.

I can only guess it's related to a modification, but modifications have never interrupted the upgrade process before so it's....strange....

Basically these appear at the end of every "section" of the upgrade.....

I've just realised the screenshot doesn't show the whole error...oops!

Try this:

Unexpected Text:

My best guess is that one of your blocks' configcache is messed up somehow. Try editing/re-saving your blocks, maybe?
