I get the "Operating in maintenance mode. Go online." message and the D7 site is not in maintenance mode.
The message doesn´t appears all the time, and sometimes it goes away when I refresh the page.
I´ve cleared cache. I´ve tested and it is most certainly NOT in maintenance mode.
I´ve checked Drupal Error reports, and I get this one (I don´t know it it´s related or not with the problem):
TIPO acceso denegado FECHA Martes, 14 May, 2013 - 01:11 USUARIO Anónimo (-) UBICACIÓN http://www.liga.net/cron.php REFERENTE MENSAJE frontpage SEVERIDAD advertencia NOMBRE DE LA MÁQUINA xx.xxx.xx.xxx OPERACIONES
Sometimes in a complete random way, as an anon, it appears the page "site offline". When I reload the page it´s up again...
Any thoughts on this will be very much appreciated. Thanks!
