The changes I made to implement big fonts may be causing problems for some users. I don’t understand what is happening so I am stepping back to the state we were in before 24 February to see if the errors go away. I apologize for the issues with “parse error” some of you have been seeing.
Those who need big fonts can still use them at http://test.tarheelreader.org.
I’ll do my best to get them working again on the production site.
