Too many redirects
Many thanks to Mark Daoust for sharing this with us.
If you are receiving the 'Too many redirects' error message, it could be that you activated an EDD plugin (specifically mentioned in the ticket was Wish List) before activating the Easy Digital Downloads plugin.
If you are receiving this error message, try deactivating and deleting your Wish List plugin and making sure EDD is activated before adding and activating the Wish List plugin again.
I had my host look into it. It was a problem with Easy Digital Downloads Wish list plugin.
I have resolved the problem on my own by deleting and re-installing the plugin.
For the reference of your company, the order in which you add plugins to the site matters. I activated the Wish Lists plugin before installing EDD which caused the problem.
