Zabbix Stopped Working

[cdm710]

Hi, I tried to login to Zabbix today, which had been working fine, but it has stopped working for some reason. It is sending me to the initial installation page and there are errors:

* mysql_query(): supplied argument is not a valid MySQL-Link resource[/usr/home/zabbix/public_html/include/db.inc.php:280]
* Error in query [select * from nodes where nodeid=0] []
* mysql_fetch_array(): supplied argument is not a valid MySQL result resource[/usr/home/zabbix/public_html/include/db.inc.php:416]

Any idea why it stopped working over the weekend?

Nevermind, it's working again this morning. Seemed like there was a problem with mysql. I'm not sure what the issue was, but it appears to resolved itself...always a plus
