If you experience blank pages, often times that is caused by PHP errors that you must track down in order to resolve the issue.

Find PHP errors by looking in your web server logs (sometimes in a file such as {{/var/log/httpd/error_log}}), or by turning on PHP error display (resulting errors are directly displayed to the browser, which is only recommended for testing environments).
Enable the display of PHP errors by doing one of the following:
* Install [http://squirrelmail.org/plugin_view.php?id=228 SquirrelMail Debugger plugin]
* Modify the following {{php.ini}} settings:
::{{display_errors=On}}
::{{error_reporting=E_ALL}}
* Add or modify the following directives in any .htaccess or apache.conf file that overrides the php.ini settings for the location where !SquirrelMail is found:
:: {{php_flag display_errors On}}
:: {{php_value error_reporting E_ALL}}

IMPORTANT: Check that the values above are not overridden by one another (any {{.htaccess}} file in your !SquirrelMail directory will override settings in {{apache.conf}}, which in turn will override {{php.ini}} settings)

For example, a blank page while visiting huge IMAP folders (to name a value, 10,000s of mails) can possibly be caused by a PHP maximum execution time error or a PHP memory limit error. If this applies to you, check also SquirrelMailPerformance.

In some circumstances configtest and login pages may fail silently and display as blank when PHP lacks session support.  Other pages will throw errors about missing session functions.  In this case enable session support in your PHP installation.
