Hi, there is a full call stack but what exact message is the error?

Jan

[vodka]

yes, that's all the debug output.
It's good that there is a backup , I hope this error will not appear in the future.

Hi, which template do you use? Each debug information includes the basics - the error message, error file and error line.
