Thank you for your reply.
Unfortunately, it’s not linked to the minify plugin (same problem after desactivation)
However, i discovered perhaps the root cause (but I don’t fond the solution for the moment)
In fact I display two times the contact part on the page estate-single-default.php
The first in a tab (behind the Details tab) and the second at the bottom of the page
The first is working well, the second (at the bottom) don’t working.
There is perhaps a conflict, I don’t know why .. I’m looking for the reason …
Perhaps do you have an idea ?
many thanks for your help
