I'm running Matrix v4.10.6, and extracted the EES version1858 into the var/www/matrix/data/public/ees folder, however I think this directory is not actually being used, since my Matrix build (following your tutorial) has all the EES files under home/websites/squiz_matrix/data/public/ees
When I create a normal design file without EES markup it works fine, but with EES markup I can only preview image. However when you click edit contents you can see everything.
This is taken from the most recent Matrix system log from the administration log asset.

Hmm, yeah, I am really not sure what is going on. Bust definitely seems like the ees files are in the wrong place unless Apache is using Matrix that is in the www folder.
I have Easy Edit Suite installed and working but when I try to preview e.g standpard page asset it shows blank.
Even previewing the the asset in the administration interface with root access doesn't show anything.
If you preview and nothing is display in either view then it sounds like there is no design applied; file assets would still be able to be previewed.
Screenshot of standard page asset page content greyed out.
The "Page Contents" that is greyed out is normal behaviour, as you do not select the Page Contents to access the asset.
