AdBlock and Fair AdBlocker are two different things. Left the link to the plugin in the original post.
Also, this add post / comment form doesn’t work/appear in stock Safari on my Mac.
Evaluating Onsen and seeing that none of the samples appear at all on /v2/guide (Kitchen Sink etc). The culprit is the Fair AdBlocker extension, which has 68K installs. Don’t know if it’s just blocking the viewer, or Onsen itself. Thought someone there might want to know about this.
Tried on Chrome on Mac and Windows.
