I originally posted on here that this plugin added malware to my site because Google's warning in Webmaster Tools indicated that the files from this plugin were infected but it didn't show the warning on any other files. However, after further investigation, this plugin had nothing to do with the malware. So I am updating this review and changing it to 5 stars, because it is in fact a great plugin. To the plugin author, I apologize for the inconvenience of my initial review!



UPDATE: This is a great plugin

Apply styles to your Google Maps with the official Snazzy Maps WordPress plugin.
