Sounds like a PHP error has been introduced into one of your theme templates somehow. Since such templates are only used on the front end, this explains the normal back end.
Edit your wp-config.php file so that WP_DEBUG is defined as true. This will cause error messages to be displayed instead of the WSoD ( White Screen of Death 🙂 ). The error messages will help you (or us) track down the problem.
Thanks, I confirmed that it is set to true already. Any other ideas?
This is happening to me too, except I get a 404 Page Not Found. I too can log into the dashboard; all functions work just fine. I haven’t changed my theme, nor have I edited it, so I don’t know how a PHP error could have been introduced. I have had Comments Off from the start to make hacking more difficult, but I wonder. Have I/we been hacked?
A hacked site is a possibility, but we shouldn’t panic, other than your site being down, nothing detrimental appears to be happening.
@friedvol – while it’s quite possible you are suffering the same issue as the OP, your symptoms are a bit different. To avoid confusion and allow the volunteers here to focus on the OP’s issue alone, please start your own topic after following the suggestions below. You can then receive similar undivided attention. Thanks.
PHP code that was valid can become invalid when your host upgrades the server’s PHP version. First ensure you are running the latest version of WP, all plugins, and your theme.
If the problem persists after updating everything, please deactivate all plugins to see if your content returns. If not, switch to one of the default themes like twentyfifteen. You should make note of your menu and widget state before switching themes. When you restore your original theme sometimes you need to manually reinstate things. The data will still be there, you just need to indicate what data to use.
If none of that helps restore content, then a hacked site is indeed a likely scenario. Start working through the steps in FAQ My site was hacked. Let’s hope it doesn’t come to this, best of luck to you!
Seems like a hack to me, this is common and happens to me all the time.
try to change the permalinks …
