Yes, Jonathan, thanks. This is what happens when I try to reinstall Jetpack (after having deleted it completely):
Could not copy file. /home/vol14_1/byethost17.com/b17_13241641/theunofficialheatherleablog.org/htdocs/wp-content/upgrade/jetpack.tmp/jetpack/_inc/gallery-settings.js
and then I continue to get the same fatal error message.
I am definitely not smart enough for WordPress…
I do not know if this has anything to do with anything, but while I am trying to resolve the Jetpack issue, I was trying to use Jetpack Lite. I get this error message:
Jetpack lite could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host.
