@lmstearn: Thanks for that info on the php code.

Here’s some info I found previously on this error (but you probably already knew this).

The ‘Are you sure you want to do this? ‘ error usually appears when nonce verification fails, and the most likely candidates for causing this error are plugins and themes not using this feature properly. Nonces are unique keys that add a security layer to protect WordPress URLs, forms, and Ajax calls from abuse.
