I need your help!

Moin Moin good friends! I had a bad interaction with the city police today! When I told you that I am a German citizen and that I don’t speak or understand Slovak. I was laughed at by the police. At the beginning of the street there was a stop ban sign. That means red border, red x and the inside areas are blue. After EU the stop ban is called. Now I parked on the walkway, which was very wide. I was not standing on the road or parked there for 2 minutes, then came city police. I should pay you immediately 50 € cash kesú. I didn’t and didn’t want to. I was convicted in Slovak with the worst ship word and boarded. I know that from my daughter, who heard the conversation. I will now ask the German embassy for help and turn to a lawyer. What I want to know about you is the following! What does this sign mean and what does it mean? Red border, a red X and the inside areas are blue. Gilt this only for the road or for the entire footpath?
