Good day to all!
People tell me what the problem may be - on the website http://pgsexpert.ru when entering the site through advertisements of advertising systems or with any type symbols?
_utmsource
or ?_openstat
redirects to the address http://pgsexpert.ru and the visit is not registered and the number is not replaced (calltracking).
It is interesting that the server with such addresses gives 404 code, but redirects to the main page index.php
Thanks in advance!
