Wordpress Maintenance Mode Problem

Your Wordpress is stuck in maintenance mode, the whole site even the /wp-admin just shows this message:

Briefly unavailable for scheduled maintenance. Check back in a minute.

Then try deleting, via FTP, the file named .maintenance in the root of the site's web folder.

That should disable the maintenance mode.

Mysql Error in accept: Cannot allocate memory

If you encounter this error: [ERROR] Error in accept: Cannot allocate memory

Then open your php.ini file and try to set higher values, to:

memory_limit = 64M
max_execution_time = 60
max_input_time = 90
