Q: In just installed 1MT PDF Viewer and configured the web viewer but what I get is an error message in the web viewer (? Line 1…)
A: this happens if you installed the add-on with FileMaker 19.1. The issue was fixed by Claris in 19.2. Please update your FileMaker Pro app (from the help menu, select "Check for updates" and follow the update process). Then re-install the add-on by clicking once more on the link in your confirmation e-mail.
