Great investigation! You can't stop the extra parameters that Facebook adds to the URLs. They are their for tracking purposes (on their part, and yours if you want to try to track Likes from users). With a little testing, I found that if I removed the following parameter from that long URL, your site would respond correctly:
&action_type_map={"10151576686529866"%3A"og.likes"}Without it, the URL looks like:
http://www.cmypictures.com/services/weddings/aziza?fb_action_ids=10151576686529866&fb_action_types=og.likes&fb_source=timeline_og&action_object_map={%2210151576686529866%22%3A507710742623527}&action_ref_map=[]I'm not sure why your site doesn't like that parameter, but I'd suggest looking in an error, security, or firewall log to see if something is blocking URLs with that parameter. Most likely, something is configured on your site incorrectly and denying URLs with that parameter when it sees it.
There's nothing we can do about this within JFBConnect, but hopefully with the information above, your hosting company or technical support can determine why your server is rejecting those types of URLs.
Hope that helps,
Alex
