Good plugin, still works well!

I like the plugin and it still works well.

I only had issues with it once when I was writing some LaTeX formulas because I used {{ … }} somewhere which triggered the plugin’s footnote expansion.

You can fix this bug by adding the last 4 lines (the upper two are provided as context) to the for each loop at the end of the php file for the plugin:

$foot_start = strpos($data, $foot_delim) + strlen($foot_delim);	//now we're looking through 'the_content' for the actual footnote text (not just inline link)
$foot_end = strpos($data, $foot_delim, $foot_start);			//find out how long footnote is
// BLACKHC: fix spurious {{..}}s in LaTeX blocks.
if($foot_start === FALSE || $foot_end === FALSE) {
  continue;
}
