That's not from our extension, but Javascript errors in other products can prevent our code from working.Uncaught TypeError: undefined is not a function mod_bestofjreviews.js:162
What is the different location? Is it a different server or a different domain? Obviously, narrowing down what is different between the site that doesn't work for you and the one that does will be critical.I have taken a backup of the portal using akeeba and restored it in a different location and tried there. It worked there. However if I use the same backup and restored it fresh on the original location, it's not working for me again. That's very strange.
Something is causing the problem and on some sites it works and others it doesn't. I wouldn't conclude that this Javascript error couldn't be related somehow just because it works on one site.With regards to the javascript error, I have another portal with the same error and it seems to work on that portal. So that error can't be the cause of this issue.
Above, your mention that the backup does work when using 6.3.0, correct? If so, there are other variables that are related here.We have similar joomla portals for different countries with different content, the only common factor being facebook login stops working after we upgraded from JFBC 6.0.2 to 6.3.0.
