Is there actually text or an image in that section already?
If not, you shouldn't get much in the html editor.
I can confirm that the HTML editor looks blank on Chrome, both on OSX and Windows 7. Works fine in Firefox, so I suggest that as a temporary solution.
I also had this issue, as did everyone on my team - any HTML editor would appear blank. We were all using Chrome and logged a Marketo support ticket about it.
They told us to clear our browser caches and that did the trick for all 3 of us.
Thanks for that update Kassia Wilhelm!
Frances Salvacion, if clearing the cache works for you, you should mark Kassia's response as the correct answer. Happy Marketing and HTML editing!
Thanks Jace! To be honest, clearing the cache did not work for me initially. But for whatever reason, the HTML editor is now back on-line in Chrome. I'll mark Kassia's comment too, though.
Hi
In this morning, I found this issue has been resolved at newest Chrome.
Try Chrome Version 43.0.2357.81 (64-bit).
Chrome is usually always the culprit in situations like this!
