Cannot create adsense ads

I am unable to create adsense ads on my site. I am on the pro plan.

Here are my page rule settings (all disabled except Full SSL):

Browser Integrity Check: Off, SSL: Full, Polish: Lossless, Rocket Loader: Off, Mirage: Off, Always Online: Off, Security Level: Essentially Off, Email Obfuscation: Off, Cache Deception Armor: Off

When I try to add an ad unit, I am blocked (although I can go back into the site easily, i.e., I do not need to log back in).

Any tips from those who have encountered similar issues? Thanks.

SOLVED: I am using Drupal and added a page rule that disables security when I go to add a block.
