I'm the admin of my server, and obviously op'd. Since minecraft 1.10.2 and now 1.11, I haven't been able to add any new shops. I use the spawn egg to select the type, place the chest, select the chest, and then select any block next to the chest like I have done before in previous versions. It won't allow me to place a shop there. I use WorldGuard and this happens within named regions as well as the global region. I'm not really sure what this could be running into, I don't believe there would be any permission problems.

They are multiple reasons why shop creation can fail:

You are trying to create a sign shop but you are clicking a block face on which no wall sign can be placed.
Depending on the side of the block you clicked: The next block in that direction has to be air.
The chest is protected: There is either another shopkeeper using the same chest, or a chest next to it.
If you have world guard restrictions enabled in the config (disabled by default): It is checking for the enable-shop flag of the region and whether the player can build there according to worldguard.

Everything else should give you a different error message. You could also turn on debug mode and see if it prints anything useful to your console when your try to create a shop.
 
And you could check your save.yml file: Sometime there are shopkeepers listed in there which can not properly be spawned. Check if any shopkeeper in there is using the same or a chest next to the location you are trying to create a shop at. Before you edit the save.yml file manually make sure that the server is shutdown and that you have made a backup.

I guess a paste of those region settings (edit: all affected regions, includes global) would be helpful.
And, are you in creative mode when creating a shop?
