The problem was solved without good explanation.
Certainly, a trial with bad nginx configuration did lead to a bad
version of jquery.placeholder-1.1.9.js in browser cache.
After correction of nginx configuration, emptying browser cache did
correct the problem.

Yes, thank you help me to think correctly.
Now I have to find why it loads one and the the other..

As you see your problem is not related to CalDavZAP - you must
check your web server documentation/configuration.
It not works only because the source code is not
loaded from the server.
Strange, I have checked that
jquery.placeholder-1.1.9.js exists and has not been
modified (dated 16 mars 00:27).
