After latest premium update, I got error when trying when trying to add new plugin through backend. Reason is that when Testimonial Widget Premium is active, it's preventing the site from communicating with WP plugins API.
I've tried to delete the Testimonial Widget Premium and reupload a fresh copy and reactivated.
But now it seems that the site is not recognising that I have premium version installed. The Testimonial Widget Premium options missing as if I have only the free version.
Free version: 2.11.1
Premium version: 1.11.0
Also now the sidebar is not returning any testimonials (it was fine before).
