wp_get_sites -> get_sites

This should now be fixed in version 1.2.5.

Wow! Amazingly quick turnaround!

Progress is good, but complicates things. For when you have the time, a way to resolve some of the unwanted complications due to this WP Core change would be to keep your backward compatibility with some checks like:

if ( function_exists( 'get_sites' ) ) {
     code using the get_sites function
} else {
     code using the wp_get_sites function
}

or if changing wp_get_sites truly was the only change you had to make to your plugin, you could do something like:

if ( function_exists( 'get_sites' ) ) {
     $get_sites_func_name = 'get_sites';
} else {
     $get_sites_func_name = 'wp_get_sites';
}

and then plug in $get_sites_func_name inplace of where ‘get_sites’ was replaced.

Your plugin is awesome so I’m sure you’re already thinking about stuff like this. Thank you for your work on it!

I have no desire to keep compatibility with older versions of WP just as I don’t really try to keep compatible with older versions of PHP. The changes required to get get_sites() working were a little more complex than your original post. Here’s the commit log from back when I made the change (I only uploaded it here because your post earlier today reminded me to): https://github.com/Flynsarmy/wp-multisite-admin-bar-switcher/commits/master

The issue in the original post is now fixed.
