[Plugin: Jetpack] Cannot enter to plugins and stats page

Hi, today I installed Jetpack plugin, everything looks great and some features are working perferctly but now I cannot access to “plugins” in wordpress, it shows a blank page.

Also in the “Stats Page” i have an error:

API URL: “https://dashboard.wordpress.com/wp-admin/index.php?noheader=true&proxy&page=stats&blog=95167481&charset=UTF-8&color=fresh&j=1:3.6&jp_lang=es_ES”
http_request_failed: “error setting certificate verify locations:
CAfile: /home/mysite/wp-includes/certificates/ca-bundle.crt
CApath: none”

But I use the debug page http://jetpack.me/support/debug/?url=mysite and it says everything is OK.

I try to change the certificate using this (I read it in an old topic):
http://certifie.com/ca-bundle/ca-bundle.crt.txt
But same problem, so I restore the certificate.

I rename the folders to jetpack-old and now I can enter to plugins page, also, the only plugin that I have is “crayon-syntax-highlighter”, the blog is new.

¿What can i do?
