Hello Ernest.
I am currently working on a local install, I even created a fresh wordpress install and added the plugin by itself. is this the latest version of the plugin? Also I installed the light version which when i save i get a Fatal error: Call to undefined function ctype_digit() in /Applications/AMPPS/www/gemsparkle3/wp-content/plugins/ajax-search-lite/backend/settings/class/type.class.php on line 94 could this be the problem with the pro version as well?
