Do you know which version of the Lithium application you are on? I know that there are some subtle differences in ActiveCast since we first introduced it a few years ago. The easiest way to tell what version you are on is to append /status/version to your community's URL. For example:
http://lithosphere.lithium.com/status/version
I know this will sound like a silly way of debugging the problem, but is it possible for you to prove two positives before proving the negative? By this I mean:
1. Can you apply Community on the left side of the page successfully by itself? Do not even attempt to put blogs on the right side. Can you have community on the left side without any other additional ActiveCast script on the right side?
2. Can you apply Blogs on the right side of the page successfully by itself? Do not even attempt to put Community on the left side. Can you have Blogs on the right side without any other additional ActiveCast script on the left side?
If you can establish both of those things as 100% true, then the next thing I would ask is whether or not there is other js on the web page which you can disable when you try to put the two ActiveCast js on the page. The idea in debugging this is isolating all of the variables that might be a root cause without first assuming it is just two pieces of ActiveCast js causing the issue.
Finally, if you have tested all of these things and have conclusively isolated the problem to the two pieces of ActiveCast js on the page, I would open a Litho-Case and/or contact your CSM directly. It is possible that it is a bug, or that one snippet of ActiveCast js needs to be futher modified because it is in conflict with another snipped of ActiveCast js.
