Hey,
The plugin was working fine on my site. I tried to change a line of text only,
<h2 align='center'>Let's Start the quiz "%%TITLE%%"!</h2>
Something about this quiz: %%DESCRIPTION%%
You will be asked %%QUESTIONS%% questions
I replaced "Something about this quiz:" with "Get ready to work on:"
And then I submitted it and now all i get is a null message.
I tried doing the same on html or visual but I keep getting the same message. I have the lastest version of your plugin Thanks!
