Solved Getting a 500 Error with PHP 7 only!

Hi
I've read the various 500 Error Entries here and still I have to post this

Everything is up to date, as you can see from the Report below. However, almost evry button - e.g. New Topic or Answer Topic etc lead to a 500 Error.

However, when I switch to PHP 5.6, the erros disappear. So I'm currently forced to use PHP 5.6
Do you have any ideas on this?
Should I wait for the upcoming Version as a solution?

Regards
David
