Any ideas?

I hit back and tried again and it worked fine but that has me slightly worried for when I do it on my live site.

I'd reupload the files. However, the only other time we've seen this, it was reading data out of the database in a corrupted way. It was some sort of server library conflict issue I believe (possibly using the MySQL client library from a wildly different version thatn the server).

 

[RobParker]

I've seen Jake reference it a few times but nothing conclusive.

It worked with a refresh, do you think that means it's safe or would you reupload anyway?

 

[Mike]

Just to confirm, when it worked on a refresh, did it still show it building the master data, templates, etc? If not, it may have just stopped running (though that shouldn't be the case with this error).

I suppose if you didn't get a warning about files with unexpected content, you should be ok in terms of the files.

I would potentially be concerned though as that's a very weird error. I suppose it could be add-on related. The only time I've seen it has been on the initial install and MySQL just completely failed to read BLOB columns. It's the sort of thing that should have come up before the upgrade in your case though.

 

[RobParker]

I refreshed and it started rebuilding templates, etc.

I didn't disable all addons like I normally would as this was just on a test install.
