Zoho is not working

Hello. Yes it’s enabled…

I don’t understand why it’s not working. I guess i’ts because my server is mutualised and maybe there is security reason that I can’t overpass.

I leave Zoho, I will find another solution ( I installed with success etherpad on my server )

But I have another problem. Maybe you could help me : Shared link : blank page

I guess it’s related, problem of right access ?

Thanks a lot for your help anyway !
