What were you doing before this happened?
I closed the page for an hour to do something else and when I came back the tabs weren’t working. Then, the entire page didn’t load. I tried loading the page with different web browsers like firefox but it still doesn’t load.
I was doing some update to my website and the site doesn’t want to load anymore.
So you were just updating content, like a post, and not a plugin or WP itself? Does the public-facing part of your site work OK? What is your site’s url?
well, I remember I activated all the plugins by mistake. I am a novice and I just want to see what each plugin did. The Url is http://www.alpfaumd.com
I also installed a new theme.
I don’t blame you for wanting to checkout the plugins. 🙂
If you can still get to Plugins > Installed plugins, deactivate them all and then you can reactivate them one at a time to find the troublemaker (if it is a plugin causing this, which seems most likely).
I can’t access the admin page at all. Is like a Blank WordPress Admin Panel
Is Guardian the new theme? Can you switch back to your original temporarily to see if that is the problem?
OK, if you can’t log in to your admin pages, you’ll need to use an FTP client (like FileZilla), or your host’s cpanel (or File Manager) and navigate to the files on the server.
In your WP installation there, find wp-content/plugins and rename that plugin folder to something like plugins-hold. That will disable all plugins and hopefully allow you to get back into WP admin. Rename the folder back to the original. Then you can start re-activating plugins until you find the problem one(s).
If that doesn’t do it, likewise rename your active theme’s folder to use a default WP theme temporarily.
what if you don’t have your FTP login information?
Is there another way to do?
If you have access to Cpanel (on your hosting account) you can use that.
