Invalid Request error - How do I recover my site?

Hi there, I’m testing Local and I’ve spent a fair bit of time building a site, and it has strangely failed - at first I couldn’t save any changes on my pages, and then when I reloaded everything it just comes up with ‘Invalid Request’ on a blank page.

I upgraded Virtualbox. Strangely, I’ve never been able to see Local’s virtual machine in Virtualbox - would I have possibly chosen a new type of config when I did the install, that doesn’t require Virtualbox?

Just to add, I’ve was using the Divi theme, and it started giving me messages saying it couldn’t save changes, so I logged out and restarted local, and now I just get the ‘invalid request’ page.

Another update, I shut everything down and restarted the machine, and it is loading again. I’m not sure what happened to cause the issue.

I still cannot see a local-by-flywheel VM in VirtualBox though, which seems strange.

Hi,
I have the same problem, have you solved it?
Thanks
