Upgrading from 3.8.9 to 5.2.1 and got Action Required popup

[Tagrel]

Upgrading my vBulletin from 3.8.9 to 5.2.1 received the following error:

Action Required Unexpected Text: <?xml version="1.0" encoding="windows-1252"?> <br /> <b>Fatal error</b>: Call to a member function fetch_userinfo() on null in <b>/home/<user>/<site>.com/forum/core/vb/string.php</b> on line <b>368</b><br /> Script: 500a28 Step: 6

Using PHP 5.6, MySQL server version 5.6.25

Installation stalled and wondering how to proceed?

Thanks,

Dave

I'm looking at this for you.

Ok I completed your upgrade for you....

You need to rename the file htaccess.txt from the download package, to .htaccess
Make sure you put the dot / period at the front.
Then upload that to the forum root so the site loads properly.

Thanks Mark for the quick turnaround. Most things are working OK - but I'm having issues with uploading custom avatars (and while many of my users work OK, many also don't show on in the forums but DO show up when I look at the User Page in admin. Very strange...
