Indexhibit Support

Hi,

i upgraded to V2 with:
indexhibit.org/tutorials/upgrade/upgrade-to-version-two/

after the upgrade the site works, but not complete ...
the files have wrong names like

old:
/files/gimgs/th-29_bildschirmfoto-2016-04-29-um-122140.jpg

new:
/gimgs/th-29_29_bildschirmfoto-2016-04-29-um-122140.jpg

Why the file have the add "29_" in the name?

And in backend i can't see the pages, but in frontend the navigation is correct?

Thank you for help

resolved: No Content in Backend
the content is ok ... my mistake

but the pictures were renamed in the database during the upgrade ...

resolved .... if i "edit" a image and click save ... the images on the page a ok ...

After you upgrade you have to visit every exhibit with images and rengerate images.
