You should not mix old versions (with different names) and the new version. You have css conflicts from doing so. You can still create copies of the new code with new names, and just copy the data from the old modules. Do not wait for a new release to fix this – it already works on every other site so there will not be any changes.
Btw – how can I fix background in summary – Can not get a html code to work 🙁 I wanted to have a color background
In the editor:
select the summary text
Click the DIV icon
In it pop up window click the Advanced tab
In the Styles field enter background-color:red;
Or you can do the same (wrap the text in a DIV with a background color) manually in the “Source” screen.
