The QuickBooks web connector is used to connect the accounting software to the web-based programs. When it encounters some issues then it throws a QBWC1085 error. In case, you have connected the data file with any third-party application then you will need to rename the QWCLOG.TXT file to eliminate the problem. Firstly, you will need to close the QuickBooks web connector. Now open C Drive and follow this path program data > Intuit > QBWebConnector > Log and then rename QWCLOG.TXT by adding old after QWCLOG. Now you may reopen the web connector and restart the computer to start working in QuickBooks.
