wp_head before closing head tag error

Thank you for the remark, I am still thinking how to handle similar responses as I’m trying to keep it low on resources (regular expressions are expensive, especially when they’re looping through many files) and there are few different edge cases, such as blank line (as in this very example) and the various comment tags – //, /* … */ and # .

I’ll probably iterate between both lines and ignore the ones starting with a comment or blank lines (can’t promise exact update date).
