Re: web sites are keep crashing

Hi AJ,

Thank you for your reply. I checked the error logs and found that site is
showing proxy error rather than showing 'site error' where there were
programmatic bugs.

In the error log below, there is a image file missing. This breaks the site
and shows 502 proxy error.

I would like to know whether we can change the proxy error to site error
which wont affect the uptime of the site.

Thanks,
Babylakshmi
