Regarding registration on this website, whenever I reach this step, the button becomes unresponsive. Whether the call sign is in lowercase or uppercase, it doesn't work. Changing browsers (Google and Edge) and installing corresponding plugins (Replace Google CDN, Redirector) also have no effect.
I'm not sure if it's a setting issue on my end, as others can open it at this stage. I have cleared the browser cache and restarted my computer, but it still doesn't work. I would appreciate any guidance from someone more experienced.
