Encountering a white screen upon opening a website usually indicates there is a PHP error with the website. Displaying PHP errors has been disabled by default for security reasons.
In order to display errors, please follow these steps:
- Open cpanel and click on File Manager.
- Open the public_html directory. If your website is in a subdirectory, then navigate there.
- From the top-right corner click on Settings.
- Check the box for Show Hidden Files and then click save.
- You should now see the .htaccess file. If you do not see it, create it.
- Open the .htaccess file and copy the code blew into it:
php_flag display_errors on
- Save the .htaccess file and exit.
Now upon refreshing your website, you can see the PHP errors. Make sure to reverse these steps after you have resolved the issue.
