I will work when you just drop the files to the right places, after renaming the custom template folder names. However, it is better practice to compare the files on by one with existing files in your installation and merge the changes. All the edits that need to be made are clearly marked with comments by the author of the mod.
Right now I don't have the time to make an update for this mod, since I have about ten other (paid) projects that need to be finished this month ;)
There is one error in the installation pack the file "default_filter.php" in the folder "template file overrides\includes\index_filters\YOUR_TEMPLATE\" should be in "template file overrides\includes\index_filters".
There is no override for this file. If you have not made any changes to this file just overwrite it on your server.
