I'm having problems in the format of the Latest/Most Comments when displayed on my site. I looked at the Demo on this site and see that it works correctly. It has a Title of JoomlaComments below "Latest/Most..." and on the demo here it looks correct, the first comment is below the heading section. On my site the JoomlaComments heading is overwritten on top of the first comment.
I would also like to know where to edit the style of how this is displayed.
I have no idea who wrote the plugin. Normally in every plugin there is a query(for latest comment) for the component it is refering to. If it is missing from the plugin then you will not see the latest comment from event list.
Sorry, but I'm too busy to look at that now. With the new version the plugins should also be updated.
