Error 500: Locked out of dashboard after activating Jetpack multisite

Hello everyone!

So I’m in a bit of trouble here… I manage a multisite network and I installed Jetpack in order to be able to display captions in WP galleries. After install, I was offered the option of activating Jetpack multisite support.

The problem is, as soon as I clicked on “Activate”, I was presented with a 500 Error. I tried accessing my Admin dashboard and all of my sites’ dashboards and was presented with further 500 Errors.

I figured I could just disable Jetpack by deleting its folder through FTP, but I am still get an error (and now I have no plugin folder as I forgot to back it up, all irate that I was).

Thankfully, the websites themselves are not affected by this, but I am under some pressure to update a lot of their content pretty soon and I kinda need access to the dashboard! Can anyone offer a bit of insight?

Thanks!
