Sorry for the late response, as we like to ignore taking weekends off but we had a lot going on this weekend.(weekends are Fridays and Saturdays)
I will sort everything out for you and update you.
We will try adding the seconds option for the Testimonials on our next update.
A lot of the CSS and JS loaded are unfortunately from the RevSlider plugin and we don’t have much control over those loading on the page.
The CircleFlip Portfolio plugin checker just looks for a different name, It have been fixed and will be launched on our next update, and if you would like please provide FTP access and I would gladly fix it on your installation now.
Thanks for your patience.
