I have built 3 websites for the same client all using identical templates and plugins.
One of the plugins is the exclude page option.
I unchecked the include box on a few 'thank you' pages I've created and they all work PERFECTLY on all three websites except for 1 thank you page on 1 website.
I deleted the page and recreated it.
I deleted the plugin and reinstalled it.
I reviewed the other 2 sites and they all have the same plugins and the thank you page in question is set up the same way on all 3 websites including having the include box unchecked.
Again, it's just the 1 webpage on the 1 website.
I suspect it's me somehow but it's very weird.
