Permission PHP Error

Hey Team,
I just installed the latest version of your plugin on a site I’m working on locally and it keeps throwing me an error. I’ve entered the purchase code and that did not fix the issue. I’ve pasted the code below and attached a screenshot. Love your plugin and use it on a bunch of sites.

(): Permission denied in /Users/danmartino/Local Sites/axcleaning/app/public/wp-content/plugins/ajax-search-pro/includes/classes/Utils/FileManager.php on line 183

Any help would be great.
