Users are getting blank screen periodically.

Hit refresh in browser and all is fine.

It seems to happen any where.

I'm on a commerial hosted site so I don't have access to everything to diagnose.

Any suggestions on how to track this down.

Can you check your log files via the control panel,
primarily if there any mysql errors.

I can't seem to find any.

The site uses phpMyAdmin to manage the MySQL DB.

Is there a way to do some sort of DB verification check?

Sounds like my hosting company. I usually run fine but regularly I get real slow performance, pages load slow and a lot of blank pages from time to time. You wouldn't be on Network Solutions would you? I realized that most if not all of the problems I encounter are caused by my host/server.

Nope I'm on HostExcellence, they have been good for a long time and if I can pinpoint a problem they usually fix it.

Is there a way to turn on debugging to get errors on web page?

I may have found the problem. PHP "Bug"

http://communityseo.com/forums/Fix-for-random-blank-pages-t3076.html

I'll quote it here for future folks doing searches.

This is a PHP "bug" (which the PHP team doesn't classify as a bug...) and can only be fixed by editing the php.ini file. You may need to ask your host to perform this edit for you if you don't have access to the php.ini file (i.e. if you have a shared hosting plan).

Open php.ini and add at the end of the file

CODE
pcre.backtrack_limit = 9999999999
pcre.recursion_limit = 9999999999

Save the php.ini file and restart Apache. Verify if the blank pages are now loading correctly.

Thanks - let us know if that corrects it for you.

If so then we may want to place this information in the manual, and FAQ - Rick/Gizmo

Well, if it works, I'll make a FAQ entry.

Sorry it was not the problem.

I'm still stuck searching for what's wrong.

Nothing in log files nothing on webpage to indicate what is failing.

Any times on how to debug this is appreciated.
