Ok no problem thanks for your help!
I managed to figure out a workaround.
1. In my case Max Galleria is in a widget on a static homepage. WordPress automatically assigns the following link
to the “next” button. “http://mysite/2”
2. I created a new page called “2”.
This new page then gets assigned the permalink “http://mysite/2/2”.
On the page editor for this new page I then added the same Max Galleria
Gallery via the ‘Add Gallery” button. Now the link from the landing
page works and directs to this new page “http://mysite/2/2”.
There is no “page not found” error.
3.In the same editor I then renamed this new page to “Gallery”. The permalink is still http://mysite/2-2 of course. But it seems to work.
It links from the “next” button on the static homepage to the new page.
