I've used your plugin for many other sites and I love it and it normally works perfectly.
However I have it installed on one of my clients websites http://www.continentalrealestate.net/ and have been doing a lot of work making sure their keywords, meta descriptions and titles are all set. I checked their site about half way through with screaming frog and none of the work I've done is showing up.
There is no other SEO plugins on the site however the template Homequest does have an SEO tab within the template itself and I'm wondering if that could be interfering with your plugin.
Any help you could provide would be much appreciated
