hey there! referring to the "security warning" thing, the same thing happened to me, and tumblr support told me that this weird code randomly appears in your theme and that's what causes the warning, and they told me that all i had to do was change my theme and it'll go away, which it did. just thought i'd save you some trouble and tell you :)
uh, i didn't change my theme but everything seems to be okay so far. but hey, i found this post and i guess that maybe it's wise to follow these instructions.
