Worlds Disappeared

After updating to the last version of Foundry, my worlds are absolutely blank!
I’ve disinstalled all the modules, but nothing changed.
Someone have same issue?

Did you confirm your Game System supports the latest version of FoundryVTT (086 Packages Testing Checklist - Google Sheets)? (assuming you mean 0.8.6). And then did you update your Game System + Modules to the latest versions that 0.8.6 needs (The Forge)?

Yes, I’ve found the problem.
Was the chrome cookie cache, I’ve cleared it and now all works fine.
Sorry and thanks.
