SEF problem with facebook comment

[Zagreb-Forum]

Unable to Link from Facebook Wall Post back to Website Comment Box ...
Comments are doing well until he turned SEF
This error occurs when returning the URL of the forum:
xxxxxxxx_metak/index.php?fb_comment_id=fbc_1015016468444xxxxxxxxxx

It would be correct if the link looks like this:
xxxxxxxx_metak/?fb_comment_id/fbc_1015016468444xxxxxxxxxx

PortaMx not safe return facebook link. Feline is very well known but not acknowledged.
If you set this code anywhere in the forum and is included PortaMxSEF, you will receive a link facebok:

Correct the error by changing this part of.

Only now are operating normally facebook comments and links to the Facebook link back to the forum.
Only Feline does not recognize the error and all the others are wrong ..
