Hi Daniel,
I checked again. I installed the plugin on a live website. No Problem.
But I could reproduce the bug on my localhost. I tried on two separate sites simultaneously on Firefox. I do not know what the sequence is, but somehow, switching the “Sitewide” flags “on” and “off” alternatively on both website, can block the plugin (on one site or the other).
@catacaustix and @ WPyogi
I did clear FF cache in vain.
Thanks for your time. That is very comforting. I am keeping on developing.
I am keeping the topic open a little while as I look for a solution.
Cheers!
