I was trying to remove a module from footer and replace it with another one. However, now everything is broken. The modules are positioned one over the other. Top on top. Can anyone advise what i am doing wrong ? Thanks
You've trashed your module but it's not permanently deleted. To get it back, in your Module Manager, on the left hand side, simply set the State to Trashed. This will show you your Footer module that you deleted before.
Now that you have it back, have a look at the the default setting that have been applied, primarily the Module Class Suffix which will most likely be the candidate.
Apply the same Module Class Suffix and and other setting to your new module
Hope this helps
