"add media" issue after upgrade


I recently upgraded my xibo server. Since then, I can’t add media, I can’t edit or supress medias. I don’t have the pop-up I should have. Did I forget something in my upgrade process ? Should I modify the database ? This is the only issue.

Thanx for your help, I don’t want to go back.

From what version to what version did you make this update?

Did you follow upgrading steps? http://xibo.org.uk/manual/en/release_notes_1.7.9.html

Last but not least, turn on debugging and have a look at CMS logs, should shed some light on the issue.
