I've succeeded in saving options in the admin panel after a modification of the source code file script.js.
I've added this line at the very start of the file script.js:
Alert ("ok") ;
(with the A in capital, yes, syntax error, yes ! )
before the first one :
I don't understand why, but it works (In fact, I was looking for a solution when I made this syntax error... )
I think it relies with a syntax error before this line (missing semi-column or something like that), or perhaps a bad script enqueueing.
I Don't know how to re-open the topic "Can't save altered options"
Hope it serves!
