Double menu

You'll want to manually update by downloading 1.7.8 in your account and then following these instructions: https://docs.generatepress.com/article/updating-gp-premium/#manually-updating

You´re absolutely right. Switching back makes it work. That is good for now, the site is working, while I can investigate where the cache is comming from.

Thank you again for awesome support, both of you!

No problem! :)

Allright, I'm stupid...
Forgot all about the above, updated GP Premium, so now I have the menu two times again...

I know my site is working with version 1.7.8, is it possible you can provide me with a link to download that version (my saved version is much older)

Shoot me an email and I'll set up a link for you: https://generatepress.com/contact/
