How To Fix Error Login Failed in WordPress Admin Not Working

Unable to get into wp dashboard or the login section of your wordpress website,here’s how you can do it with simple steps

Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).

One of those should fix the blank Dashboard.

If so try:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems?

if not try:

– switching to the default theme by renaming your current theme’s folder in wp-content/themes using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

If still problem exist then Try increase PHP memory in WordPress

Open wp-config which is located in the root WordPress directory and add below code

define('WP_MEMORY_LIMIT', '64M');

If that doesn’t work, try downloading WordPress again and delete then replace your copies of the /wp-admin/ and /wp-includes/ directories with fresh copies from the download.
