Drupal 7: Wrapper for an HTML file

I was looking for a wrapper for an HTML file, like Joomla offers.

I found a way to load an existing HTML file into my Drupal 7 site using a module called insertFrame.

insertFrame

In /admin/config/content/formats/full_html select the box Include iFrame with auto-height feature.

Then add
[[[http://www.myurl.com/myapp.html]]]
to a page or post.

I still have a weird error message to fix:
Notice: Undefined offset: 1 in _insertFrame_getHTML() (line 118 of /myurl.com/sites/all/modules/insertFrame/insertFrame.module
