XF 1.2 unserialize(): Error at offset 0 of 1 bytes

[TPerry]

I have started getting a TON of the above in the error log whenever I install a new add-on.
I tried rebuilding the master data and got the below.

Server Error

Anybody have any ideas (short of trashing the DB and starting over again from scratch with the entire site. My other two forums are not doing this (each on an individual dedicated server but all running the same OS and server related files).

Had already reviewed that - and nothing has changed other than a few Debian updates that came out - but if that was what it was I would be having problems on my other servers also (since they are all configured identically). Have just done a dump of the DB and am re-importing it (this is an existing forum that was working fine).

It's possible that there could actually be corrupted data in the style properties for some reason. I'm not sure how it could happen - without checking, it could be related to a property that was a string value and is now a complex CSS property? Reverting the offending property would sort it, though identifying it might be tricky. You could use "customized components" to see if there's anything that jumps out.

I'm leaning now towards a problem with digitalpoint's map add-on. I think it's conflicting with another add-on and causing problems on that one forum. When I have it installed I'm getting an error from it. Just removed it from the system and am now adding another add-on to it to check to see if the same error crops up again.

EDIT: and no error crops up with that add-on removed. Now will try a rebuild master data to see if I get the above error again.

EDIT #2: Rebuild Master Data ran fine this time - so apparently it is something with that add-on. Post entered in the resource discussion for that add-on reflecting the error.

@Mike, I think you hit the nail on the head. What I ended up having to do was export the style and then import it again - overwriting the original one. I haven't had any additional errors reported (been running for about 9 days now) after doing that.
Thanks!

I have the save error updating 1.21 to 1.33. Tried everything listed here but nothing helps.

What else could I try?

Did you read Brogan's resource guide to upgrading from 1.2 series to 1.3 series and follow it?
That's the very first thing that you should do (if you haven't already).
