ha!
You just remind me.
All templates are actually file based and I call them uncached with [[!includeFile]], as I needed it that way when developing the site

.
Even the chunks! I only have a very minimum chunks amount. It’s only 2 chunks right now.
I don’t like edit chunks on MODX’s manager.
And you should realize that there is still the ’recusive JSON’ bug on the chunk editing page.
Go check your modx’s error log
AFTER you edit any chunk.
Anyway,
If you’re interested to join developing the site, it’s better that you PM me your private email, so I can send you the whole site package to be investigated (thanks to the @splittingred’s PackMan

).
PS:
I just edited the templates, you can check the site again now.
