You do have two Testimonials Lud (TL) on that page. At least, head scripts of TL section are loading twice, witch is causing error.
Its the way the Pagelines Framework works: if you put section in the sidebar (or header or footer), this section will be loaded on every page, even if you don't use sidebar on those pages. That is why you get transition error.
solution 1: don't use TL in sidebar if you planning to put TL in content on any page.
solution 2: if you want to keep TL in sidebar, but also want to show TL in content on other page(s)
- go to wp-admin and edit page that should have TL in Page Template or Content Area.
- scroll down to PL Meta Settings. On Page Setup tab you will see two Testimonials Lud: one in the Template/Content and one in the Sidebar. Disable one in the sidebar and save. That should prevent loading TL section twice on that page. Screenshot: https://www.dropbox....screenshot1.png
