sites not being updated automatically after changes

Hi,

when I do some changes in the settings like the footer or the sidebar, the change doesn’t take place until I go into each side, do an update on the backend, go back to the frontend and load it again. I’m not sure if I describe the problem correctly but when I for exaple change the appperence of the footer, I need to go into the backend of each side, update it, load it again and then the change take place.
Same thing with the weather widges I installed. They don’t update either until I go to the backend -> update > refresh.

I encouter the issues on this webside: http://neue-wordpress-homepage.de/, the weather widges are installed on this page http://neue-wordpress-homepage.de/spielberichte-und-neuigkeiten-mansory/.

Thanks and best regards

Alexander
