Enable defer of JS files for Pagespeed Insights

Hi,

All that function does is to add a javascript code to the page, so I don’t think it’s related. In terms of php code it uses a few lines of very normal code and I can assure you it’s working in many sites flawless.

What do you mean by “cannot login”?
Is it a white page, wrong user / pass, some other error?

If there’s a white page, you can remove the plugin by deleting the fast-velocity-minify directory inside the wp-content/plugins (by ftp, hosting control panel, etc).

If you get a white page, there might be some php extension missing on your server, which is not a good thing. Please make sure you’re running PHP 5.6 or above.

If I enable this function I have an error “Invalid username or incorrect password!”

I rename your plugin and the website do work again

That’s quite strange… are you trying to log in using the default yoursite.com/wp-admin/ OR yoursite.com/wp-login.php OR are you using some other form on the site to login?

Are you using Google Chrome OR some other browser?
Does the login fail if you try from another device (mobile, tablet, etc)?
Have you cleared you browser cache and tried again?

That’s the only way for me to check what’s going on.
You are the first person to have this problem, so unless it’s a cache issue it must be something server related.
