There is certainly a lot to take in while setting this up. It's not all that complicated, but if you take the time to read about what it is doing, there is a lot of information there.
I did find that there are other plugins that can complicate things.
I have gotten a couple of notices that have directed me to have WP Super cache update its Mod Rewrite rules. But it gave me a link right to the page to get that done.
I also had a warning that the readme.html file was not protected, but did not offer a solution. It ended up being a conflict with Better WP Security (Wordfence has been suggested as a better choice).
All in all, it seems like a powerful solution. I am most impressed with the level of support that is offered in the support forum. Kudos to AITpro for that.
