Attempted to guide him, I reached a error 500 (blank page) and the following exception:

Hope you can help him with this. 😄

Sorry for late reply @petzsch & @dsbaars. This seems like a problem with the referenced BTCPay Server submodule not being up to date. I've bumped version there and published update of Voucher plugin. @dsbaars can now give it a try and let me know if it works for him.

@dsbaars can now give it a try and let me know if it works for him.

Unfortunately it still doesn't. I get a similar error in the log file as was already posted:
