Common WordPress Login Page Issues

I've noted some common WordPress login page issues. Here's the list of them.

Page Redirection or Continuous Reload

The login screen continues to refresh after you log in, but the login doesn't complete. Or, it takes you to the homepage or another page.

This happens when:

• Cookie issues.
• The URL for the site and the URL for the home page don't match.
• A caching plugin is saving the wrong session.
• A rule in .htaccess instructing the server to redirect.

How to Fix it:

Here's what you can do to fix this issue:

• Delete all the cookies of the browser.
• Temporarily disable the caching plugin.
• Check for mismatched database URLs.
• Create a new .htaccess file from Settings > Permalinks

White Screen on Login

You see a blank screen after login. This happens due to PHP errors.

These PHP errors include:

• Conflict with plugins or themes
• Exhausted PHP memory
• Corrupted core files

How to Fix it:

Here's what you can do to fix this issue:

• Increase the PHP memory. I.e; (define('WP_MEMORY_LIMIT', '256M')).
• Disable all plugins via FTP.
• Switch to a default WordPress theme.
• Enable debug mode to see the error.

Login Credentials Not Working

How to Fix it:

Here's what you can do to fix this issue:

• Reset password via phpMyAdmin

403 Forbidden Error on Login

This happens when your server blocks access to wp-login.php or wp-admin.

This issue might occur for:

• IP blocked by any security plugins.
• Incorrect file permissions.
• Server firewall settings.

How to Fix it:

Here's what you can do to fix this issue:

• Check .htaccess rules and remove blocks
• Disable security plugin via FTP
• Set correct file permissions (e.g., 644 for files, 755 for folders)

500 Internal Server Error

This general error can crash your login and admin pages.

This issue might occur for:

• Plugin or theme with fatal PHP error.
• Broken .htaccess file.
• Low PHP memory limit.

Here's what you can do to fix this issue:

• Rename the .htaccess and log in again.
• Disable all plugins.
• Increase memory limit.
• Turn on debugging to trace the error

Unresponsive Login Button

You've entered your credentials. But the login button does nothing when clicked.

This issue might occur for:

• JavaScript conflict with a plugin or theme.
• A broken login form.
• A Browser extension is blocking script.

How to Fix it:

Here's what you can do to fix this issue:

• Try in incognito mode or another browser.
• Disable plugins via FTP.
• Switch to a default theme.
• Temporarily turn off all browser extensions.

Quick Pre-Checks Before Troubleshooting

Before troubleshooting, do these following checks to avoid extra hassle.

Clear Browser Cache and Cookies

Old cache data can block proper login sessions. Clear them fully.

Try a Different Browser or Device

Browser-specific issues or extensions often cause login problems. Testing elsewhere rules this out.
