PHP 5.4 Support?

Hi all,

I am using the “Twenty Eleven” theme for WordPress and am hosted through Bluehost. I received this from Bluehost today:

“If you’re not certain of your sites compatibility with PHP 5.4, you can quickly and easily test it by changing your account to PHP 5.4 single using the outlined steps below. If, after changing your PHP version to 5.4 and your site looks normal and operates without any errors then your site is compatible. If you update to PHP 5.4 and you find your site showing errors or a blank white screen that is a good sign that something in your site is not compatible. Most commonly these are plug-ins or themes that need to be updated. Switch the PHP version back to 5.2 and login to your admin panel and check for any available updates. If none are available you will need to check with the plug-ins/theme developer to see if they have compatibility with PHP 5.4.”

Following their instructions, when I change it to 5.4 and check my site, it is completely blank. I switch it back to 5.2 and it works fine.

Any ideas? Do I need to change themes?

Thanks in advance!
