You do not have sufficient permissions to access this page

Hi all,

i have a very strange problem that going me crazy.

I have installed a wordpress intallation correctly into my local web server ( xampp with linux os version ), i haven’t installed plugin or theme into it ( uses default theme with not plugin ). Then i have trasfered this wordpress installation to remote server under a domain and to do it ( i do it normally) i followed these steps:
1) Transfered with FTP all directories and files from my local web server to remote.
2) I exported my database from local phpmyadmin in .sql file, i opened it with an editor programm and modified all url like as example http://localhost/../ in http://www.mydomain.com
3) I created a database with user ( with all privileges ) on my remote server and then i have imported .sql file already modified.

Till these steps there aren’t been problems, so if i go on my domain/site i can see it and navigate it perfectly. I have only problem if i try to enter with right credentials into my wp-login.php file
i receive this warning message:
You do not have sufficient permissions to access this page

i have already checked all documentations about this problem, i have seen that user hasn’t problem, that wp_capabilities is a:1:{s:13:”administrator”;b:1;} and wp_user_level is to 10 so there aren’t other problems, but if i try to access into wp-admin i can’t.

I don’t know where is problem, and i have tested all of possibilities.

I ask someone help to fix this problem.

Maybe could be some problem with grant permission with mysql user ?

i haven’t ssh access into remote server, but i don’t know how could be this problem, if i export database in a .sql mode from a local server and upload it to remote database.

Hope in some help.
Thank you.
Regards
