Hi, I'm trying to get this extension to work on MW 1.38.x. I get a similar message as 109.253.216.196; it provides a link to the twitter page, not a display of the content. See e.g.: https://csdms.colorado.edu/wiki/Test41

Seems to be working fine for me. Could be an anti-tracking or similar script blocking it.
My apologies! My browser is blocking the content and just provides a link. Sorry for bothering. I'll add 'Solved' to the question. Thanks!
