How do you contact a Poptropica creator? - poptropica website template

I bought a "multiverse" in Poptropica site, and the work at first place. But now, if I pull the code, "it says there is room for your contribution" ... What's happening? Poptropica I spent my credits earned for this function, and I want it to work properly. So my question is: how to design Poptropica? I want to inform them of this error. Thanks for the answers!
