Wordpress login error

Hi
I have tried to login to my wordpress site and received the following message:
Briefly unavailable for scheduled maintenance. Try again in a minute.

Can anyone help me with this please. Not sure what is going on?

Thanks
Roop

Not really sure if it is an issue with the theme. Because theme can’t recognize any server maintenance period. Probably you could check it out with your web hosting support department?
