Ever try to access your wordpress admin panel, and it just pops up with a horrifying blank screen? The solution may be even simpler than you think. In most cases, if you can still access the site, but your admin area is blank, it’s the file “functions.php” in your theme. Even one blank space after the final “?>” at the end of your theme will cause the WordPress admin menu to be blank. Solution: Use an FTP program or your hosting company’s file manager access to remove any trailing spaces.
If you’ve verified that there are no spaces either after or before the “” of your functions.php, and/or the website itself is not displaying on the front end, then you’ll probably want to contact either a developer or your hosting company to find out if it’s a malicious attack or just a coding error somewhere within the website.
