I’ve started to receive this notice on my site. I’ve had to disble the plugin for now to prevent the error from showing to customers.
Notice : Function register_rest_route was called incorrectly . The REST API route definition for fv_endpoint/v1/fvforceupdate is missing the required permission_callback argument. For REST API routes that are intended to be public, use __return_true as the permission callback. Please see Debugging in WordPress for more information. (This message was added in version 5.5.0.)
Yes, both are on SIteGround’s GoGeek plan. It hasn’t been an issue before, just cropped up out of the blue. I know nothing about REST API or PHP. I’m just a hobbyist with knowledge of HTML and CSS.
