My issue is that I can't login to the admin panel, I know that this is already asked, and I have tried:
- Clear cache and sessions,browser cookies.
- web/cookie/cookie_domain and web/cookie/cookie_path clear in the table core_config_data
- i will check the session path its correct
but still same error.

Possible causes :
Local computer time vs. server time mismatch, causing instant cookie invalidation. Make sure your server time is correct.
Incorrect permissions on var/session, preventing session files from being saved
Incorrect configuration of database/redis/other session storage, preventing saving of session values
A module is instantiating sessions to early, preventing the correct session names from being set
You're a developer using multiple URLs and have multiple cookie domains
Another developer has somehow modified app\code\core\Mage\Core\Model\Session\Abstract\Varien.php, creating a hard to track down bug
The cookie domain in
System -> Configuration -> Web -> Session Cookie Management
doesn't match the actual site domain.You're using the localhost as your server domain, and using a version of webkit that has trouble/bugs setting cookies for localhost in some situations.
The short term fix is to just delete your cookie for the domain. That's often enough to solve the problem. If it persists, figure out which of the above reasons is the reason for your error.
Use HTTP only
' to 'No' in 'System->Configuration->Web->Session Cookies Management' of the 'Web' settings.Reference
