Hi Comite5!
First, which steps have you taken so far based on the
Upgrade Guide? Can you provide some more details about what is going wrong with your interface, or any errors that you are seeing?
Second, one of the breaking changes between 7.6.2 and 7.6.7 had to do with server side rendering (SSR) configuration (see
DSpace 7.x Release Notes) - so you could double check if you need to update your
SSR settings.
Last, just to note DSpace 7.x is
no longer actively supported, which means it will not continue to get bug fixes and security patches. Because of this when possible, we recommend upgrading to at least DSpace 8.x whenever possible.
Best,
