Error when subscribing to blogs

[Conner]

Users get this error when they subscribe to the blogs:

Site Title- - BlogsWarning: array_merge() [function.array-merge]: Argument #1 is not an array in [path]/blog_subscription.php on line 879

What's causing this?

Anyone? Or am I going to have to figure this one out on my own too?

You'd think after paying so much for a license, support would be just right around the corner. vBulletin support has died down a lot in the past couple of years that I've seen.

What version of the blog and forums are you running? Have you tried uploading the non-image files again to ensure it's not down to a corrupted file? Are you using a custom style or the default?
