Gallery plugin not working?

Hiya,

I have tried posting in the plugin support forum but it seems quite dead so I wondered if anyone could have any ideas for my problem.

I use the plugin Tiles gallery, and recently with upgrades to my template, it has been overridden by the default gallery. Here is an example:

I don’t suppose anyone knows why this might have happened?

Thanks,
Jack
