WP Tiles & Theme 'Twelve 14' conflict help

Hiya,

I’ve tried posting in both the plugin and theme forums but no one is replying so hoping someone can help.

I’ve installed the gallery plugin WP Tiles. It displays OK:

https://www.jackwallington.com/test-gallery/

However it seems to also pull in elements of the page (e.g. headings and code for other plugins, like a social one I have installed). In addition, it doesn’t seem to be compatible with the light box gallery plugins I have installed.

It feels like there is a simple conflict between code or javascript…

I wondered if anyone has any ideas?

Thanks very much!
Jack
