Error in login page after activate Rank Math Plugin

Hello,

We apologize for the inconvenience you are facing after activating the Rank Math plugin. It seems like your email address is automatically populating in the login page’s email field, even in incognito mode. This issue might be related to a conflict between Rank Math and the Ultimate Member plugin you are using for login and signup.

To address this issue, you can follow these steps:

1. Reconnect Website with Rank Math:

   • Go to your WordPress Dashboard → Rank Math SEO → Dashboard → Help.
   • Click on “Disconnect Account” to disconnect your website from Rank Math.
   • Then, click on “Connect Now” and follow the prompts to reconnect your website with Rank Math. Make sure to select the correct account and activate it.

2. Check for Plugin Conflict:

   • Sometimes conflicts can arise between Rank Math and other plugins like Ultimate Member. You can check for conflicting plugins by following this guide: List of Conflicting Plugins.
   • Additionally, you can check for conflicts with themes by referring to this article: Plugin/Theme Conflict With Rank Math.

If the issue persists after following these steps, please let us know, and we will assist you further.

Thank you for bringing this concern to our attention.

Hello,

Thank you for contacting Rank Math support, and sorry for the inconvenience this may have caused.

Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.

If the issue persists, then we might need to take a closer look to the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
