Recently we had a staff member get a script error when logging into AccountRight with their account.
We've gone through the following steps to resolve with no resolution:
1. Reset account password
2. Delete all browser data via Internet Options in Control Panel
3. Added site to Trusted Sites
4. Uninstall, and manually remove appdata files, then reinstall
The is easily reproduced by using this specific account on any other workstation, even if it has never had AccountRight installed previously.
If another users email is used, it can login just fine.
Hopefully anyone here can share some further troubleshooting steps while I wait on hold for MYOB support.
