I migrated about a thousand items with attachments from K2 using your tool and attachments plugin. I initially did this on a test account. Everything worked fine over there. The migrated article attachments worked fine. Then I backed it all up and moved it to my live domain. Now none of the attachments load. All I get is Exception File Not Found and I can't figure out where to look. Turning on error reporting and debug don't tell me anything. I am guessing the old files were not moved during the migration correct? Or how does that all work? I still have all the original folders in the original places as far as I can tell.
An error has occurred. 0 implode(): Argument #2 ($array) must be of type ?array, string given

Any idea what's causing this?
