Thanks @gemmaevans
When I try to install Jetpack in my wp.org I have no problems, but when the istallation is over it says that I have to ‘start up’ Jetpack, it says exactly this:
You’re almost done. Set up Jetpack to boost your site performance and unlock powerful customization, marketing, and security tools.
Connect to WordPress.com (free) to set up Jetpack and get started!
By clicking the Set up Jetpack button, you agree to our Terms of Service and to share details with WordPress.com.
Set up Jetpack Start quick tour
after clicking ‘set up Jetpack’ sometimes goes error 504 (in wp.org)
or 500 in (wp.com)
thanks for the help
