"You have entered an invalid character such as < or >"

<p>I keep getting this message any time I try to "Save and Check for Errors" in a supplement and it's driving me crazy. Once when filling it out for the fifth time in a row, I decided to just leave the whole thing blank and it STILL said I had an invalid character. How can there be an invalid character if there were no characters entered? Is anyone else having this problem?</p>

<p>What supplement are you trying to complete?</p>

<p>Any supplement for a specific college including Pepperdine, Puget Sound, University of the Pacific and Ithaca</p>

<p>I was getting the same thing the other day, just a bug on their end I guess</p>

<p>Did it go away?</p>
