I recently installed wf-section 2.07b3 on XOOPS 2.0.15 and, after a regular installation log, I can't create any section, because the section management interface doesn't exist.

I installed also wf-section 2.01 but there was the same problem.

some hint?

Suggestion: Abandon wf-sections. It's like fitting a lawnmower motor to a Chevy Suburban - they just aren't made for each other. Wf-section was excellent a year or more ago - no slight on wf-section at all. WF-section stopped development some time ago and, if I remember correctly, was effectively taken over for development by the folks at SmartSection which can be found at http://smartfactory.ca/.

Make sure to get the latest version of SmartSection, too. 2.0.15 had some changes that created issues with some of the smart modules. There is a preview of both SmartSection and SmartFAQ out for testing to make sure the 2.0.15 issues are fixed. So, I guess what I'm saying is, go with SmartSection but you should probably wait (I'd imagine just a couple of days) for the stable 2.11. If you can't wait that long, try the preview (knowing of course that it is just a preview). Still, IMHO, the preview will be a darn sight better than WF-sections.
