I may have a similar problem. In the video it shows the options like above (b / link/b-quote and more: Color, padding, etc.). Now I no longer have those options. I probably chose a plugin that did this horrible thing! But I do not know how to fix it or get back to the way it use to be.
Before I hear from someone, I may deactivate all the plugins and replace them one by one.
I am trying to get an online store prepared. I am using Ready!ecommerce (sp?) and deleted Woocommerce. Perhaps that is the problem. I am at my wits end.
