Hello. We 've installed the module but we have some issues, as we use Journal theme. 

What kind of modifications should we make in order to appear to other themes?

Hello there,

If the issues that you are having are related only to the design of the module, then you just have to style it in order to look like the other modules from Journal. However, if you have other issues, please open a support ticket in our site, where our support specialists will be more than glad to help you.

Hope this helps!
