The WordPress login page refreshing and redirecting issue is a common problem that many users encounter.

This usually happens when you try to login to your WordPress site. Instead of accessing the dashboard, you’re redirected back to the login page.

Here are several possible solutions for this problem:

1. Clear Cookies and Cache: The most common cause of this problem is corrupted cookies and cache. Clear your browser cookies and cache and then try to log in again.
2. Deactivate All Plugins: Sometimes, a poorly coded plugin can cause this issue. Try deactivating all your plugins. If this solves the problem, reactivate one plugin at a time until you find the problematic one. Once found, you can choose to keep it deactivated or replace it with a different plugin.
3. Revert to a Default Theme: If deactivating plugins doesn’t solve the problem, try switching to a default WordPress theme (like Twenty Twenty-One). If this solves the issue, the problem is with your theme.
4. Update Site URL: If none of the above solutions work, try updating your WordPress site URL. You can do this by adding the following code to your wp-config.php file (replace example.com with your site URL):

   define('WP_HOME','http://example.com');
   define('WP_SITEURL','http://example.com');

5. Check .htaccess file: A corrupted .htaccess file can also cause this issue. Try renaming your .htaccess file to .htaccess_old. If this solves the problem, go to Settings > Permalinks and click “Save Changes” to generate a new .htaccess file.
6. Enable Debug Mode: If you’re still unable to resolve the problem, enable debug mode in WordPress to see if any specific errors are causing this issue. To enable it, add the following lines in your wp-config.php file:

   define( 'WP_DEBUG', true );
   define( 'WP_DEBUG_LOG', true );
   define( 'WP_DEBUG_DISPLAY', false );
   @ini_set( 'display_errors', 0 );

This code enables debug mode and creates a debug.log file in your /wp-content/ directory. Any WordPress errors will be saved in this file.

Remember to take a complete backup of your site before you try these solutions. If you’re not comfortable making these changes, consider hiring a professional or contacting your hosting provider for assistance.
