Not sure, but usually a blank screen is a CSS issue with another plugin or the theme. Revolution Slider recently caused a similar issue that was fixed by updating the slider plugin.
If possible, please complete this form to have us take a look at the installation, or try disabling other plugins to see if you can find the cause. If it is not a plugin, then try changing the theme, and let us know what you find so that we may try to duplicate and fix the issue.
We remain at your service.
