My WordPress site is not loading!! Please help me


Staff member
my site was running smoothly until yesterday night but suddenly it lagged and I tried in many different browsers by clearing cookies and caches to load it.. It still does not load up... I checked the admin panel error log and it displays that
[Mon Jan 26 13:40:53 2015] [error] [client x.x.x.x] File does not exist: /home/coventry/public_html/test/500.shtml

the site i'm working on is <a href="" rel="nofollow"><a href="" rel="nofollow"></a></a>

Also I noticed in admin panel lvepmem is full as it indicates red colour (1,022.6 / 1024 MB). lvemem is 1,301.2 / 2048 MB..

Please it would be great if someone could help me with this... Thanks!!
