[Koha] Problems with Issue after upgrade to 2.2.6

I have upgraded Koha to 2.2.6. Now for some reason I cannot issue books. I select the patron to issue the book to, type in the barcode for the book, and Koha responds barcode not found. When I do a catalog search for the barcode, it finds it just fine. Is there a Koha to MARC DB link that I am missing now, or something else? skaman
