Entire site goes white, with single word: Error

Hey Better WP Security Gurus,

My entire site went down today, with nothing but a single word: “Error” showing up on a blank white page.

This error message appears on the site front-end, login page, etc.

Since this kind of thing is normally caused by a corrupted plugin, I went through my plugin folder, disabling one at a time, looking for the problem.

Then I discovered the site whiteout is being caused by Better WP Security.

I am running the most current version of WP, and of Better WP Security. The plugin has worked brilliantly on my site for months. I haven’t installed any new plugins, or changed versions or settings on any of my other existing plugins.

This plugin has been a godsend, because my site is hit with MANY hacking attempts per day. I would love to get it back up and running, and really (REALLY) don’t want to have to uninstall the plugin in order to get the site functional again.

So: a few questions:
1.) Do you have a list of plugins that have known conflicts with Better WP Security? Perhaps there’s something else I can uninstall.

2.) Do you have any suggestions to remove the “error”? Is this caused by an overflowing log file or something simple?

Any advice would be appreciated.
