Not working

So, I am using wyvern chat for already 3 days, really good interface and great proposition in the free model but right now it's being 1 and half hour that the site isn't working none char load (even the images or title), the favorite ones show but when click to chat change the page and nothing shows up in except of the superior menu, I changed wifi,5g and browser nothing see to help, I also didn't find any update warn so I don't really know what is happening
