XFileSharing Pro - Lots of problems installing script in subdomain

[genaginger]

Hi,

I have version 1.7 on my main domain and i want to upgrade to 1.8 so i thought to first test upgrade on a subdomain i followe every instruction and installed script

i have some problems after installs

1. I can register fine but unable to login it seems some session problem
when i try to loginwith wrong user and pass it says me error thats right

but when i login with correct login i can see url in url bar chnaged to ?my_files but login box still appears

i can see session data entered in session tables
but it dot appears login

but when i go to CheckAuth function and make a die $sess_id i see it has diffrent session id then id in session tables

now if i manually put the session id i copied from die $sess_id to session table to right user row then i can see i am logged in and i can go to my account

but as soon as i try to go to ?op=admin_settings i receives error:

Software error:
Can't call method "SelectARef" on unblessed reference at Modules/Session.pm line 244.

Please suggest me what could be wrong

Login page: probably you're using invalid url? Try your site address without any ?my_files.

SelectARef problem: get the latest ZIP and update Session.pm from it, this should fix the problem.
