Iframe for image in announcement not showing in OJS 3.0.1

[ctgraham]

You can use Google Drive to host images directly via an img tag rather than trying to mess with an iframe (which is bad practice). See:

If you really want to use an iframe, you will need to modify the HTMLPurifier library. See:

Iframes not showing up in ojs 3.0.0

I tried adding youtube video to an announcement in my ojs 3.0 installation. The problem is that I can clearly see the frame (and video) in the “editing window” of an announcement in my administration panel, but it is not visible in the main webpage. here is the link to my journal: www.npwtj.com is this a bug or did I miss something like allowing iframes somewhere? server is ec2, ubuntu instance.
