I want open a new thread, its not possible, why?
When I do it, its just refresh the page and I have to start from 0

You have just done that, havent u?

I guess u have some rules broken or something in the post. Try disabling some plugins or changing browsers, maybe it disables JS/something else

Yeah here it worked, but in the plugin section not. Idk why. I can answer on threads but not open one. I dont think I broke rules here

You cannot just create threads there. You need to create them on specific plugin help page (open any plugin page and press "Help")

misticos, I know how to make a Thread, but its like I said when I do it, its just refresh the page and I have to start from 0
