JSON conflict with WYSIJA plugin

I haven’t had time to look into this. I deactivated Filebase when this error popped up. WYSIJA is a newsletter plugin. See: http://wordpress.org/extend/plugins/wysija-newsletters/

It came up when I tried to send a preview of a newsletter created in the WYSIJA plugin. I am using the SMTP send option with WYSIJA.
