Data content not rendering on the webpage: Server not replying back

My page is made in php, I hav开发者_开发知识库e qcodo which is layered on top of my database for the website. Occasionally, the webpage does not render and instead of the content it should display it displays the website URL in the body. This problem started occurring after I added few fields in the database. At first I thought this might be a qcodo problem, so I tried qcube on a test page but the problem was not fixed.

Can anyone point me to right direction, I think it is the server that is not sending a sent content message to the client.

No errors? Try to turn on error and warnings.

If the error is not consistent then it could be your web/db server is busy.

Uhm, something very similar happened to me long time ago. It ended up it was due to an empty line that was somehow appended to one of my .php files.
