I use DupeFreePro for many tasks. Do you need to know why your webpage is not displaying your new code that you entered in?
With DupeFreePro I use it to compare the previous coding to the new coding to help me figure out what the error is or what I missed.
I also use it to compare two articles to see how much one is different from the other. This helps to decrease duplicate content.
So many options – DupeFreePro is a must during each work day for me.
Hope you like it too.
P.S. This is a free software – you will not have to pay to have this – you may want to unsubscribe from their mailing list – that is your choice.
