# HTML Template Preview Problem

* While using WordPress 3.9.1, I am unable to see a “live preview” of the HTML
template. The Thickbox does open, but the only content displayed within the iframe
is the text “undefined”.
* While investigating this myself, I noticed that iframe src refers to the file“
preview.html” within this plug-in’s directory on the server. In my case, this
file exists, however it’s entirely empty. I would have to assume this gets written
to temporarily by the plug-in. The permissions on the file “preview.html” is -
rw-r–r–. Could there be a problem with the permissions or the owner/group of
the file/entire plug-in directory?

* Hello grant.tom,
* I have no issue with the latest WordPress release. I don’t think the file permissions
are involved in your problem. Did you try to clear your cache ? Also try to give
the ouput your console (firebug in Firefo or devtools in Chrome).

* I think I am having the similar problem. I can see the ‘live preview’ of the
HTML template. But when I send an email in HTML format, it doesn’t show up the
format I set in the HTML template.

* Could you be more specific? I’m not sure to understand your problem.
Please
try to install test this on a clean WordPress installation.
