In my case the issue was that the file had Unicode encoding. Changing it to ANSI fixed the issue.

Actually yes, there is:
Instead of placing the plugin in …/wp-content/plugins/ you put it in …/wp-content/mu-plugins/ (You may have to create that directory, if it’s not there yet.

Plugins that are placed in mu-plugins are ALWAYS run, so the only way to deactivate a MU plugin (MU currently is construed as “must use”) is to delete it (or remain the directly mu-plugins to something else…).

Hi Jonathan,

You will need to save file as .php. Please use a different text editor on Windows you can use Notepad or download Notepad++. On Mac, you can use TextEdit or download and install TextWrangler.

You don’t need to copy and paste line numbers.
