Hi Bart,
First, apologies for the lateness in reply. This is my first plugin and I hadn’t subscribed to the forum.
Would you mind sharing what you have entered as the WP_SITEURL and WP_HOME? These should have an https:// in front of them and have everything up to the /wp-content/…..
e.g. “https://www.exampledomain.com”
That’s great that you would like to use it in your development process. I have a number of changes planned as a result of using it in the development team I lead but it would be great to get others input as well.
Nick
