After upgrading the Kaseya server from 6.2 to 6.3 the 2FA Addin is not functioning properly. Under "Modify Agent Groups" the dropdown menus do not expand properly, several pages may load slower than normal, and several scripts are not executing correctly.
This Kaseya server has an older version of the Addin installed. With Kaseya 6.3 there were several changes made to the website and database structure, and the older Addin files do not account for this. Open up the "About AuthAnvil Addin" section inside Kaseya under "AuthAnvil" or "Two Factor Auth". If you are running v188.8.131.52 or earlier then this version is unsupported in Kaseya 6.3.
Contact Customer Support for the latest version of the AuthAnvil 2FA Addin for Kaseya (v3.6 at the time of writing this article). When you receive the installer, running it will prompt to uninstall the previous software first. Make sure it is fully removed and run the installer again to put the latest version in place.
Note: The new Addin will prompt for a schema rebuild at the end of the installation. Remember to advise your users on a brief interruption in Kaseya usage during this process.
AuthAnvil Two Factor Auth Addin for Kaseya v184.108.40.206 and earlier.
