I was able to solve this problem by checking my wp-cache-config.php. Upon checking wp-cache-config.php, I saw that the contents became binary codes. I was able to revert this by using the code that was saved from my localhost server.

I installed a WordPress blog in my local system. But when I try to add plugins from admin it asks for FTP access. What do I need to configure for WordPress to be able to upload without FTP?

Someone made some wp wlwmanifest.xml http requests, but why? Ask Question Asked 5 years, 4 months ago Modified 2 years, 9 months ago

Set the permissions for wp-config.php to 640 so that only wp-user can read this file and no one else. Permissions of 440 didn't work for me with above file ownership.

The user that is running your web server does not have permissions to write to the directory that Wordpress is intending to create the plugin directory in. You should chown the directory in question to the user that is running Wordpress. It is most likely not root. In short, this is a permissions issue.

I was able to access wp-admin but after entering user/pass it redirects to wp-login and showed empty screen. I reset the password, enters the new password and it worked.

Note that wp-config.php can be one placed one folder above wordpress installation. Using wp-load.php or wp-login.php might be a better option.
