Thanks for the speedy reply Lance:
I noticed the 4.3 upgrade shortly after posting this thread and performed the update. I’m still unable to get any of my “Results Layout” to be reflected on front end. I took a peek at the database and saw that option was being saved successfully and my changes appear in the admin page under “Experience > Results > Appearance”.
Another thing I tried was to enable WP_DEBUG constant, but no errors or warnings related to SLP. Any other suggestions on where I might look? This seems so glaring that I’m hoping it’s an oversight on my part.
Thanks again.
