Moved away from WordPress.com and image carousel now not working

The site I’ve put together is all about local history photos. I started the site using the Twenty Eleven theme on WordPress.com where the photo carousel works fine, but have moved to a local host so it is now ‘Pro’ and renamed tiptontimeline.co.uk
In my original site (tiptontimeline.wordpress.com which is still there) when you click on an image it enlarges to full size with arrows left and right to show the other images in that block.
After site migration if one clicks on an image nothing happens, so if looking at a wide photo (e.g. old school photo) you cannot see the rest of the image. This applies to all photo gallery blocks on the site so is a big problem for me!
I’m now starting to go back in time to earlier decades/years so there will be loads of photo gallery blocks for this local history website.
Can you help me with this please?
