Hello,

 

Since yesterday I have a problem with my  back-office admin page . I log in then I click dashboard and the page disappear , shows me the "kCFErrorDomainCFNetwork303" . I clean the caches and nothing. Any Idea how can I solve this problem? The site it works fine as a visitor but I can not open anymore the admin page.  I have prestashop 16.1.9 . I have Prestashop 8 months now and everything works fine since last weeks I get a lot 504 time-out on back-office and yesterday the "kCFErrorDomainCFNetwork303" . Did anyone knows what going on? 

Thanks in advance,
Jona

You are using which browser ? If it is safari, than upgrade to latest version. If you are still having same problem, try with another browser.

This error could be also a https2 server error. You should host your site on a http1 server. http2 protocol is not yet supported over all networks, furthermore there are some incompatibility with caching.

Hello,

 

Thanks for your answer. Yes I have Safari  11.1.2 (13605.3.8) I think it's the latest version. I run the Google Chrome  and it works fine if you clean caches often. So Safari cause that! Interesting! Thanks again for your reply!
