Everything works perfect on production server.
Need to copy the project to localhost to dev enviroment (xampp).
1) Copy all files to local folder
2) Export/Import DB with phpmyadmin
3) Change pathes in /blablabla/config.php and /config.php (blablabla - the name of admin folder)
4) Delete cach in /storage/cache and /vqmod/vqcache and /vqmod/*.cache
Site works prefect, no problem with layouts, no any php errors/warnings/notices.
I try to login to /blablabla/ area, and can not: after submiting Login form I am redirected to /blablabla/index.php?route=common/login without any error.
The same story is with customer login, - redirecting to login form after submitting customer’s login form.
I truncated oc_sessions and did many other attempts, but I am still not Logged In

Help, please.
What this can be?
