Thanks @sturader. I thought it was worth mentioning, because Andy obviously does care a lot about producing an excellent user experience. Since he knows what to expect when testing, he may not understand the confusion points for someone not used to the products. Also one plugin appears to have a changelog out of sync with it’s version number. This may just be an error from the plugin author, or it may be something Andy needs to look into – I leave that entirely up to him to decide!
I’ve now had a chance to play around a bit with the blog and portfolio shortcodes as used via Visual Composer, and they’ve worked perfectly for me in all scenarios.
I did notice that when I switched off the portfolio excerpt display it left a blank space where the excerpt would have been. This is a subjective issue, and might be outside the intended scope of these shortcodes. I resolved it with
.entry-summary {display: none;}
