…yet a bit more…I did run updates on the local site from WP 4.9 to 4.9.1 and Connections.
What I have just noticed is that WP seems to be altering the quote structure within the shortcode. It doesn’t matter how I save it – text or visual, it will alter them. So, I’m guessing either there is something funk in my shortcode that WP feels like warrants it changing it or, WP is just doing it because it wants to. I will inspect the shortcode. I don’t know if i can do anything if the problem is the latter.
Have you heard of any issues with long Connections shortcodes being altered in the editor of 4.9.1?
