If a blank page appears instead of your website, do the following:
- Check whether the file you are opening is not empty. If it is empty, restore the file from a backup.
- Make sure that the following PHP parameters have the values recommended below:
- display_errors sets whether PHP error messages shall be displayed in a browser. To enable error displaying, change its value to On or 1.
- error_reporting defines what types of diagnostic messages should be displayed in a browser. To enable displaying of all types of messages, change its value to E_ALL. This value is equivalent to 2047 for PHP version 4, 6143 for PHP versions 5.2.* and 30719 for PHP versions 5.3.*.
More detailed information on allowed values of the error_reporting parameter is available on the official PHP website at http://php.net/manual/en/errorfunc.constants.php.
Once the parameters' values have been changed, refresh the blank page. Any error messages that may appear will help you understand the cause of the problem and eliminate it.
- Clear Smarty cache in WebAsyst Installer section "Diagnostics -> Clear cache". If cache deletion does not work, please follow these instructions to delete cache files manually.
