Troubleshooting the QuickBooks Web Connector and Sync

To start troubleshooting we recommend that you enable notification/ logging in QuickBooks Web Connector, this will help to identify the problem and assist in a speedy resolution. To enable logging in the QuickBooks Web Connector go to File > Enable Notification.  Once notificatoin is enabled the Web Connector will keep a log of each time you attempt to update.  We may ask you to send a copy by email of the log to support to assist us identifying the cause of the problem.  You can also see a summary of errors from the last unsuccessful sync if you click on the "Click for more information" link in the Status panel of the Web Connector.  Here are some of the more common errors and advised actions:

A modal dialog box is showing in the QuickBooks user interface. Your application cannot access QuickBooks until the user dismisses the dialog box.

This application has not accessed this QuickBooks company data file before. The QuickBooks administrator must grant an application permission to access a QuickBooks company data file for the first time. QuickBooks needs to grant the Zed Office web service permission to access your company file, you must be logged onto QuickBooks as the administrator to do that, go to Preferences > Integrated Applications and select the Zed Office web service and modify the permissions. Then retry an update.

To reset this click on the Remove button and then reload your QWC file and enter the correct password. If you continue to experience this error then contact Zed Office support.
