Error - White screen after login

With the work team we have been using passbolt for a long time and a few days ago it stopped working in both chrome and firefox.

When logging in it gives us the passbolt logo but the rest of the page is completely white.
But we can see the passwords if we click on the extension

hey @Luis.vazquez.f welcome to the forum!

This issue is very likely due to your server being on version 2 and your passbolt browser extension recently updating to at least version 4. The best solution here for you is likely going to be to update your installation or to migrate to a new server which is on the latest version
