I've seen the “Unhandled script exception" / "SCRIPTS – data area” / “Exception_Class_Script_Addressing" errors show after an upgrade to GP 18.2/18.3 due to the PM00200 table not receiving the new VENDDBA column it should have, so you can rule that out, running this script against each company if you are currently on 18.2 or later for GP:
Select VENDDBA, * from PM00200
Otherwise, does this error show anything more below what the screenshot is showing? Dexsql.log?
If you have third parties or customizations, you can try renaming the GP directory after getting all users out, and then run a Repair against that GP install, which will completely re-create the GP directory without third parties nor customizations, even without modified forms/reports dictionary files, then login to the 'new' GP directory and see if you can re-create this message.
If you can't, then it may be a third party or customization that is causing the issue and you'd need to add them back to this 'new' install, one by one, testing after each one, until you identify the cause.
Let us know what you find out...
Thanks
