I’m using the most latest version of the Easy Testimonial plugin, with virtually no complaints.
I integrated the Twitter Bootstrap framework into WordPress, and developed a website for a client of mine. I had previously disabled the Cycle2 Javascript file (found in the Settings of this plugin) during testing.
Turns out that it had also caused my mobile navigation to not work properly. Once I had re-enabled Cycle2, my mobile nav worked fine (i.e. it appeared!).
No complaints or issues, but I thought this might serve as a useful heads up for others.
