But Julius35’s description fits my problem 100% and I’m of course not saying, that he (or anyone else with this problem) should not try your suggestion.
I’m only trying to help by sharing my experience.

Do you want me to start a thread of exactly the same topic anyways?

I reset the options (although the paths were there before, too).
I also loaded these scripts in my header “by hand”.

All I get is” Uncaught ReferenceError: nextgen_lightbox_settings is not defined ”

Same problem here.
