Sorry if I'm putting this in the wrong place!
I help run a website with around 2 - 4 million page views a month. It's a heavy database driven site and users carry out a search and then go on to do certain actions. We're using PHP and a MySQL database, and have a couple of dedicated linux servers which manage the volume.
We have a problem though of sometimes seeing "blank pages". It can be at any point on the site, or by clicking on any link. Sometimes it's at the start of a process, sometimes at the end. If you refresh then you get the right page displaying, but we have no idea or clue why this is happening.
We've done some research, but nothing has been uncovered. Does anyone here have any ideas on what could be causing it?
Any thoughts would be greatly appreciated as I'm hitting my head against the wall here..
