Krileon, thanks for the prompt response. I think we may be at cross purposes, you've fixed 90% of the problems, groups are correctly visible and accessible by the relevant groups from gj. The majority of groups are correctly visible and accessible from kunena. There are now just 5 exceptions out of 35. (3 of which relate to admin)

The only bits remaining are a couple of permission issues but you've fixed all the other permission issues but we don't understand what you did to make them work. e.g. admin previously could not access the All councillors forum from kunena but after your last visit they can so you obviously fixed something. Is it possible for you to explain what you did as you fixed so much?

Would the permissions bug explain these 5 instances?

Most users can correctly access the correct forums from either gj or kunena with no permissions errors which they could not do before! The only thing not working is a member of the clerks group can see but not access the forum from kunena. We can live with admins not accessing from the forum!

We will test the creation of new groups and do a clean install as suggested, this will take a few days so bear with us but we will report back.

We will also delete the old fireboard records in the db which the conversion to Kunena left. This is the only site where the forum was upgraded from fireboard. We have not had any problems on newer sites where fireboard was never installed.

Many Thanks

We've backup live and restored to a dev server.

We created a new group in the admin backend. Correctly recorded in kunena categories.

User joined ok and accessed forum from gj ok. user accessed forum from kunena with no problems. Created post in forum, saved ok and correctly shown in gj.

Tested view access rights with another user - kunena no view gj display correct i.e. works

Then User created group in gj - nested, published at backend. kunena correctly includes in categories.

Whatever you did seems to have fixed the group and categories issue between gj & kunena
