Job description
There are two things to be fixed
1. The contact form does not work, something is interchanged with the fields probably, it does not show that the fields are filled. In addition, it shows the voivodship badly, it also needs to be repaired
2. There are errors in the functioning of articles (read the choice of color, eg pavement tiles between gray and white), choices that are designed in the store do not display correctly, the store does not show when the selection is unavailable (eg the model has one color, I choose another one it has 5 colors) and you have to shoot in order to get the right choice so that the store will let you to the next step of the order.
I require an earlier backup, so we could prevent leaving errors. Repairing obviously mentioned sub-points and describe whether there have been any changes in the Core code / Modules changed and where.
