This is not the problem the OP has, there are no errors in the Chrome Inspect console for his site. As Laza et al already saw there is no trace of jabum bridge in the source.
I did run into a problem with nothing appearing when I placed my jalbum albums on another site. The new site is only containing jabum albums, and the working url was inserted in a jalbum bridge line on my WP site..
Nothing showed but the console showed an interesting error:
No Access-Control-Allow-Origin header is present on the requested resource
and the .json file could not be read.
Googled it and implemented the simplest solution:
Add a .htaccess file in the root of the server with as content::
Header Set Access-Control-Allow-Origin "*"
This works for me, Apache server. For other servers more complicated lines may be required.
So if you see such a problem, Chrome has an excellent Inspect facility with the Console tab showing errors in your page. and this may help you solve the problem!
