Can't load new modules on the eshop site

Since it didn’t work that way before, I tried copying the content of the application/views/blocks/details_productmain_tprice_tpl to modules/ak/views/blocks/details_productmain_tprice_tpl, so I changed the path too. I took the example of the organization of the other modules in the project. Also, I thought it would look neater if it is all organized in the modules/ak/mysaving folder.
Oh, and the " is a mistake… as I copied the content, I mistook the two single quotes for one double quotes, so I quicky tried to fix that. Then I realized it was ok the first time. Sorry…
