We are testing the upgrade to 2013 from 2010 and have completed the database upgrades in the new farm. Everything works, however when you click on someone elses mysite the activity for that person displays as HTML. i.e.
<a href=http://mysite.company.com:80/person.aspx?accountname=DOMAIN%5CUSERNAME title="JOHN DOE">John Doe</a> added 4 new colleagues.<br/><a href='http://mysite.company.com:80/Person.aspx?accountname=DOMAIN%5CJane Doe'>Jane Doe</a>, etc.
Anyone know how to fix this?
