Plugin works but too many glitches

I invested between 3 & 4 hours trying to tweak the plugin’s configurable settings based on the plug-in documentation.

I was unable to make the plugin fully function. For example, when writing a post on the front end, not 1 but 2 images would upload (very strange but not acceptable)

The whitelisted posts in setting doesn’t work, at least not with my theme.

I tried around 25 variations of short codes as instructed in the plugin documentation but none made the plugin function to my needs.

I simply wanted a custom post and image but it just did not work.
