I have the version 2.7.1 installed long ago in 3 domains, it was working perfectly without any interruption till day before yesterday. When I tried to access the blogs yesterday both admin and frontend got stucked for admin I cant access eventhough typing the correct login credentials. I have tried to overcome this by changing the password from PHPMyAdmin using MD5 that also failed its not recognizing the admin email id also.
I have no clue what was happened suddenly, is there any issues in 2.7.1 after the release of 2.8.1?
Please help me to resolve this issue.
