This document provides information to help you troubleshoot any issues you may be experiencing when using the site. It is an ongoing project and information relating to additional common issues will be added as needed.

For help with issues relating to any of our plugins and services, please see the relevant documentation sections.

Error Messages On-Screen

If you are having trouble logging into, the first thing to check is if you see any error messages appear on-screen under the Username/Email or Password fields.

If you do see such errors, check for any typos in the credentials you have entered.

For example, when copy/pasting a password from another document, it is quite common to get an unwanted blank space before and/or after the copied text. To unmask the password field, click the eye icon at the far right of that field.

Errors in WPMU DEV login form

You can also try resetting your WPMU DEV account password by clicking the Forgot Password? Link.

That will pop open a form where you need only enter your WPMU DEV account Email address and click the Reset password button to receive an email with a private link where you can change your password. Then try logging in with your new password.

No Error Messages / Spinning Loader

Too many failed login attempts lockout

If you don’t see any error messages appearing on-screen, or if the loading spinner just keeps spinning, you may have gotten temporarily locked out due to too many failed login attempts. In this case, you won’t be able to log in even if you typed in the correct credentials.

Wait for a few minutes and log in again.

Possible Browser Issues

If you are sure your login credentials are correct, try logging-in from a different browser, or an incognito or private window in your current browser.

To open an incognito or private window in any modern browser, click the vertical ellipsis or burger icon at the top-right of your current browser window and select the Incognito or Private window option.

For example, this is how it looks in Chrome browser.

If logging-in using a different browser, or via a private or incognito window in your current browser works for you, that means that something is stuck in your browser cache, or your browser cookies need to be cleared.

Possible Firewall Issues

It is possible that the firewall feature in your anti-virus program may be causing issues.

Try temporarily disabling the firewall to see if you can then log in. If you can, you’d want to add an exception rule to the firewall to allow connections to

Possible Blocked IP Address

To check for the possibility that your IP address has been blocked by our system, try logging in from your mobile device or a computer on a different network.

If you do not have access to a mobile device or a computer on a different network, try restarting your router to get a new IP address assigned to your network and try logging-in again.

If you are able to login from a different device or network, please contact our accounts team as seen below and provide them with your IP address. They will verify if that IP is indeed blocked on our systems.

Other Possible Issues

If you are using Chrome browser, try disabling QUIC in the browser.

  1. Type chrome://flags/ in the browser address bar.
  2. In the search box, type quic to locate the protocol.
  3. From there, use the drop-down to change from Default/Enabled to Disabled.
