Can this broken theme detector message be turned off by the plug-in author?
According to the link provided with the alert message, the wp_head() and wp_footer() are not required and not included in every theme. From the codex:
This hook is theme-dependent which means that it is up to the author of each WordPress theme to include it. It may not be available on all themes, so you should take this into account when using it.
Also, when I tried to add it to my theme, it messed other things up and didn’t turn off the error message.
Thanks! Great plugin!
