thanks for response
I installed both version of phpvms . v5.5 and v2 and test some skins but when i activate them, all of site crashed and show some line and errors
yes,it is ok on default skin
phpvms v5.5 : testcrew.iatva.ir
and phpvms v2 : crewcenter.iatva.ir
I installed them in other subdomains to skinning them and test all,when they are ok without any problem move one of them to main subdomain
