    Did the error appear only once during the plugin update? That’s caused by some code in QM running before the update and some after the update.

    I’ve made some changes recently to reduce the chance of that happening, but if you’re updating from an older version it can still happen.

    Hi John,

    yes, the error only occurred when updating the plugin to the current version.

    We have updated from the last current version to the most current version.

    Maybe this will help you a little further in troubleshooting.
