I can't see css changes

Hi. My english is very limited, sorry.

BLOCS does not display css changes. Instead I can see them in the browsers. It happens, above all, with the color changes of the texts.

Mojave 10.14.4
Blocs 3.2.4

That sounds like a cache issue inside Blocs. Does it still happen if you restart Blocs?

I have restarted the application several times but I have to check if the solution you give me works.
When that error occurs, the color of the text turns white and if I copy and paste it, it is solved.
