I am using 2.3.0.2. OC. When I try to edit the status of the product to "On stock" and hit save I get an error ERR_BLOCKED_BY_XSS_AUDITOR or I am redirected to the missing page. I am using Chrome. It is up to date. I tried the same in Firefox, the same thing happens.
Is it some how connected with token and API?
I tried the whole new API thing but does not work for me.. I first noticed this thing when I moved to another hosting . They are saying it is nothing to do with the server, but probably with cloudfare??
If I try to edit the item it redirects me to a broken page of mine.. my site looks like this originally..

but when I try to save the edited version it redirects me to this and saying The page doesn not exist, so it does not save it...

I would appreciate some help.
