I've been using Jetpack a lot in the last year, on different blogs, without any problem.
On my last blog - here's the address - Jetpack is not working properly, for what matters the Tiled Gallery module.
I've downloaded and activated correctly Jetpack and all the other modules: they work. But if I try to use tiled gallery there's simple no options in the post to choose from. No layout options, and so on.
It's like the module simply isn't there, but I've activated it. I tried uninstall and reinstall Jetpack, deactivate and reactivate the module, but to no avail.
I've no strange plugin installed on the website. I even tried to deactivate Alpine PhotoTile for Instagram - the only other plugin that could be loosely related to that - with no results.
Any idea? I really don't know how to handle this.
