Troubleshoot Froala editor oEmbed plug-in

I'm using Froala editor on my Wordpress site and I want the embedding to be similar to how the default Wordpress editor runs. Wordpress uses oEmbed. The Froala oembed package was installed from here [login to view URL], but it's not working on the front-end posting form. Nothing is appearing when I tried to embed anything. I need that to be fixed. You can see the posting form by clicking on the + button on the bottom right corner of the homepage. Currently there is an Embedly plugin as well that works with Froala, but I want to see if the Froala-Oembed plugin works with my site. Once the post with the embedded content is posted, I need it to show properly on the front end post display. A couple of other things to fix: After opening a post on the lightbox, going left or right stops working after two or three clicks. Google Chrome usually has the yellow background colour on the textbox when logging in. But the site doesn’t remember my password even after I tell it to.
