Hello. Thanks for helping me. About test before buy i could say that when i bought joomsef it was version 3.8.2 and everything was fine. The problem occurred after upgrading to version 3.9.2 moreover i started experiencing trouble with virtuemart extension - process of checkout didn't work. I solved it to set $allowUTF = "1"; Now i try optimize my site and it is very inconveniently every time to connect via FTP and manually editing configuration.php . My provider is using PHP v5.2.10 and certainly i tried to use MOZZILLA, IE9, Opera browsers but without effect. Also i turned on show PHP errors on web server but nothing to found.
Do you have any ideas to help me?

Why i should use to paid support if i use paid version of JoomSEF. It's very strangely. What is the necessary version of PHP for JoomSEF 3.9.2 ?
