Problem after copying translation to my theme

[Baarssen]

I copied the dutch translation from comunity theme to my own theme.

After this i got something very strange: https://www.screencast.com/t/pyrr038RhpW

Al the backoffice menus wher changed to english in adminmodus, in my shop i cant see profiles anymore: https://www.screencast.com/t/FF90ssA9ff

Also my shop doesnt show the products anymore, so i think something happened that shouldnt be this way.

How can i role back this?

In productcatalog i get this message:

[ThirtyBeesException]

Root category must be an integer value at line 345 in file classes/helper/HelperTreeCategories.php

1. • @version 1.0.0 Initial version
2. */
3. public function setRootCategory($value)
4. {
5. if (!Validate::isInt($value)) {
6. throw new PrestaShopException('Root category must be an integer value');
7. }
9. $this->rootcategory = $value;

I solved it for myself by reinstalling tb again, but i remember it went wrong sometime ago with another shop.
