I only wanted to redirect my customers to a page after checkout. The plugin someone recommended to me is not updated up to 4 WordPress versions earlier so I needed an updated plugin and I found this yesterday. After I installed and activated, it redirected all links on my site to the homepage, I couldn't access any other page. I deactivated it but the problem wasn't solved. I then thought the problem was from my hosting provider. Not until I deleted the plugin this morning, did my website go back to normal. Yith better do something about this, it's not fair. I almost had a heart attack because I didn't have a recent backup of my site.
