Settings broken / mail.zoho.eu/zm loads very slow

Hi,

I cannot reach settings page and when click mail set filter etc... browser say errors such as:

POST https://video.zoho.eu/isactive.do 404 (Not Found)
VM4210:1 Uncaught SyntaxError: Unexpected token / in JSON at position 0
settings.js:1 Uncaught ReferenceError: ReactDOM is not defined

Page is blank and does not load.

Also when i goto webmail https://mai.zoho.eu/zm loads very slow.. takes a minute or more before i get to inbox..

please have a look
thanks in advance

P.S. I cannot seem to register here in forum because i have zoho.eu acccount?!
