   I've run into an incompatibility with the wp-footnotes plugin that for every search gives the error:

   Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in /path/to/directory/footnotes.php on line 167

   It's the same issue mentioned here: http://wordpress.org/support/topic/plugin-relevanssi-a-better-search-relevanssi-and-wp-footnotes?replies=3

   But I don't understand the solution. Can anyone help, please?

   Many thanks!

   Adding @ before the function suppresses the error message. It doesn't fix the problem, just hides it.
