Resolving Zip Manager Queue Locked Issue
If you're attempting to add items to an empty Zip Manager queue and encounter a message indicating that the queue is locked, this issue may stem from cached data in your Web browser. To resolve this, clear your browser's temporary Internet files (often referred to as the "cache") and delete any associated cookies. After performing these steps, click the "refresh" link on the Zip Manager page and attempt to add items to the queue once more.
By clearing cached data and cookies, you facilitate proper synchronization between the Zip Manager and your browser, allowing for accurate queue status updates.
