tracker problems after upgrading 12.8 -> 15.2
after upgrading from 12.8 to 15.2 I've several problems with my website.
the most important is that I cannot administer trackers anymore:
- cannot create new trackers
- cannot duplicate trackers
- cannot manage fields in existing trackers
- cannot filter existing lists anymore
(another problem is that the wysiwyg editor is not working, it hangs 'loading'. the tracker problem is now more important, because I've disable the wysiwyg editor. I mention it because these problems might be related?)
Could somebody set me on the right track?
my website is 'www.open-onderzoek.org'. The menu option 'WESP rapporten' gives an example of a tracker-list. If you try to select a filter, you can see that it doesn't give an field to enter a value.
