Need help finding a bug.
Website randomly does not load page, just makes a blank page, but loads on refresh... no logic to when it happens.
Linux, Apache,Php 4.4.7, fusebox 4.
Script works fine in variety of testing environments, not on live server. Not an option to update to fusebox 5.
Current programmer thinks it is server problem, server admin thinks it is a script error.
Need second opinion and help identifying the problem.
