Don’t bother, i have found the source of the problem, event if i don’t understand the real cause…
During the final adjustments, i had set a htaccess/htpasswd to restrict access to the wordpress directory. This was the cause of the bug…
When i removed the htaccess to allow you to access my site, this resolved my problem ;D
Thank you again for this wonderfull plugin, wish you an happy life and as they say : long and prosper !
