I experienced a similar problem in v 17.12.74 when trying to view themes under Settings, but got a different error message:

I can view the Plain theme, but neither other built-in themes nor custom themes. However, they all work when selected while viewing transactions in other tabs.

I have put this issue into the Bugs category.

UPDATE: This is still a problem in v18.1.0. Also, the problem only occurs when viewing active themes. Inactive built-in themes can be viewed without any problem.

Thanks Tut – have just tried 2 different invoice themes in a “dummy business” set up, but same result as before system crashes…

Should be fixed in the latest version (18.1.3)

solved - thanks
