Thanks, John
I cleared the cache, the CloudFlare cache and deactivated css compression (think it was this issue) and reinstalled the plugin.
It is working perfectly (screenshot).
Sorry for the annoying and thank you for directions!
Hello,
1) The plugin stylesheet loads perfectly, the problem was with the template style sheet.
2) No, not at this time it is not installed.
I’m using the free version of Pinnacle, only changed the options on the theme of the panel.

3) I honestly do not remember to perform an update during the period, in fact the plugin worked in the early days (installed it earlier in the week) and today I noticed that no longer worked.
I thank the attention.
I discovered that the problem was related to plugin “Instagram Feed” developed by Smash Balloon, version 1.3.11.
When disabled, the theme returned to work perfectly.
