We have web site with CraftCMS Pro 2.6.2930. Due to development of new site, we set test web server (Centos/Apache/mariaDB) in our local network and migrated whole site there for testing (2.6.2993 with trial license). Site is working, but logins to craft admin webpage are rejected (log in button is greyed out).
For migration i have followed this Migration of Craft CMS from one host to another (we deleted license.key file)
Craft/storage/runtime/logs shows
2018/05/17 13:45:58 [warning] [application] tried to log in unsuccessfully.
Site content is migrated successfully.
PS: I've already tried this and it isn't working: Reset password with MySQL
Any ideas?
PS: It seems my problem is very similar to this one Control Panel access. Greyed out button since i see (almost the same) errors
