I'm new to Wordpress and I'm not a developer. I'm running an IFTT applet that posts a WordPress post each time I upload a new video on my Youtube Channel.
There is a bug with IFTT. It often posts the same post 2 or 3 times.
Therefore, I'd like to avoid duplicates before they are published. I read on forums that I needed to add a XML RPC plugin.
I tried this solution (Set up on Site B) XMLRPC Avoid duplicate content
I added the code using Insert PHP Code Snippet Wordpress plugin.
But it doesn't work for me. I still have duplicate posts coming in.
I also created a plugin file and it doesn't work either.
