Civitai can not appear in the front page of Stable Diffusion

After I download civitai extension,it still can not appear in the fornt page of Stable diffusion,is there anyone could tell me why?Many thanks!

Have you restarted your UI?
The other thing is to check your logs on your instance, maybe it existed before and is giving you a SOCKET IO error ..
Also, it's LIKELY ONLY to show up in a small icon at the TOP RIGHT corner of your SD instance.. with a little red or green dot over the Civit logo.

Hope this helps!
