A white or blank page indicates a script problem on your website. To elaborate; typically the page is blank because your script is causing a fatal PHP error and the error is being hidden for security reasons rather than shown to the browser. Though no error is presented to your browser, you will typically find an error_log file in the same folder as your website which will contain a printed list of all errors. These errors need to be investigated by your website designer/developer who should be able to use the information to determine the cause of the problem.

Please be advised that ThisWebHost cannot assist in diagnosing or debugging these white/blank page issues. These are script related errors and are not an indication of a general hosting problem but rather a problem with your websites code.
