Plant Theme isn’t working properly?


I’ve been working on the plant template, and isn’t working properly.

The product page images are not loading as it should, once you click to change the product image everything hides.
And in the other hand, some parts of the site must be refreshed to load correctly. I cannot expect that my users refresh the site every time it stops working.

The guide online does not help me at all.

Please could you help me?
