Hello Vincent, thank you very much for your answer
My workflow is kind of very simple everything was working well until yesterday and I changed nothing.
I have a search-box on one page where the user can write a geographic adress. I save the adress like a parameter called a.
On the second page this was working until yesterday and it stopped to work :
This is an exemple with a city called Lyon in France, it should display the Escape Rooms at less than 50km of the city but it just display all my database. Everything was working well yesterday and now all the users can’t do geographic search 
Do you know if there is another way of doing it ?
