Thumbnails of Product Page are not clickable

[Lportela]

Like the tittle says, the little thumbnails of the product page to show other angles are not clickable. It's shows the little mouse hand but it wont open.

Theme Dawn

Don't know if its related but I recently put a code that don't allow to zoom images and right click save as 

Although I rolled back to the original, the problem still persist.. also like the code that don't allow to zoom images and right click save as 

Shouldn't this be rolled back to ?

I think I may done something that I shouldn't done.. I'm not any expert in code. just google and copy past

Also in the Default Product Page this error appears. Already rolled back to the original and he still persists

I dont know what to do.. any help?
