How do you fix the occasional blank page when submitting a form?

The most troublesome bug is the occasional one; there is no definite way to reproduce it.

I've searched a lot on this topic, and the most probable reason is the charset, and I've taken some actions by setting the default charset as utf8 in .htaccess (I'm using Apache), but it still happens, again occasionally!

Have you guy开发者_运维问答s any tips other than setting the default charset to fix it?

As a side note that according to my own experience it happens mostly when the form is submitted from IE, if not all.

Are you using PHP?

Usually any time I hit a blank page, it's because there's an elusive bug in php someplace and errors are turned off.

Just an alternative path you might investigate.
