Hello,
We apologize for the issue you are facing with logging into your WP-admin due to the Rank Math plugin. It sounds like there may be a conflict or a redirect issue caused by the plugin.
Here are a few suggestions to troubleshoot the problem:
-
Check for Plugin Conflicts: Sometimes, conflicts between plugins can cause issues. You can perform a quick conflict check by disabling all other plugins except Rank Math and see if the login issue persists. If it resolves, enable the other plugins one by one to identify the conflicting plugin.
-
Theme Conflict: The issue might also be related to your theme. Try switching to a default WordPress theme (like Twenty Twenty-One) temporarily to see if that resolves the login issue.
-
Clear Cache: If you are using any caching plugins or server-side caching, clear the cache to ensure that you are not seeing a cached version of your site.
-
Check .htaccess File: Sometimes, redirection rules in the .htaccess file can cause issues. Check your .htaccess file for any unexpected rules that might be affecting your login process.
-
Debugging Mode: Enable debugging in WordPress to see if any errors are being logged that could give you more insight into what’s happening. You can do this by adding the following lines to your wp-config.php file:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
After enabling this, check the debug.log file in the wp-content directory for any errors.
If none of these steps resolve the issue, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.
Thank you for raising this concern, and we hope to help you resolve it soon!

Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
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.
