Hi Jonathan, 1) The SQL query, SELECT COUNT(*) FROM issues WHERE borrowernumber=516 results = 3 2) At the OPAC (when patron login), it shows counts = 3 3) At the Koha Administrator, Patron, Check-out page = 3 4) At the Koha Administrator, Patron, Circulation history = 9 (this is the actual number of books borrowed by the patron) 5) At the OPAC search (without login) for a particular barcode which is not shown in patron's OPAC but picked from Patron's Circulation history for which status shown as "Check-out", is displayed as: "AVAILABLE" in OPAC. I guess, the problem started after migration from 16.05 to 16.11.09. before that, during previous semesters Koha behaved excellently, did 22,000 transactions during last one year. The problem reported with Check-In. when performed check-in, the barcode/books details was not removing from the patron's account. after that Check-out counts. Now, all the OPAC's terminal's are kept shutdown, until it is fixed. And only satisfaction is, it is showing correct check-out counts in patron's page and opac login for the recent Check-outs. After update from 16.5 to 16.11.09, during last week of July, whatever books issued for those accounts I am facing problem. Not sure, how to proceed further to fix the issue and appreciate your feedback. -Satish
