Important Error jump from groupjive

I've upgraded fireboard 1.05rc2 to K 1.0.10. When I access the forum directly there are no problems. But when I access the forum from Groupjive a message is displayed: "You do not have access to this forum!".

I went through other threads and modified the class.kunena.php:

1.

$options[] = mosHTML::makeOption($item->id,kunena_htmlspecialchars($item->treename));

to

$options[] = mosHTML::makeOption($item->id, $item->treename);

(at two locations)

2.

$parent = mosHTML::selectList($options, 'catid', 'class="inputbox fbs" size="1" onchange = "if(this.options[this.selectedIndex].value > 0){ forms[\'jumpto\'].submit() }"', 'value', 'text', $catid);

to

$parent = mosHTML::selectList($options, 'catid', 'class="inputbox fbs" size="1" onchange = "if(this.options[this.selectedIndex].value > 0){ this.form.submit() }"', 'value', 'text', $catid);

But this did not do the trick. Any sugetions?

Does Kunena even work with GroupJive?

Yes it does. A quick google shows the answer.

G'day, alfons I recall the discussion where the technique you described was introduced. In that case, though, GroupJive wasn't mentioned as a factor.

This is a bit of a long-shot: may I enquire if, in your case, you're hosting your website with Joomla 1.0.15?

Sorry for the fact that I haven't provided enough information:
Linux Server
MySQL 4.1.22
PHP 5.2.9
Joomla 1.5.9
Community Builder 1.2
Groupjive 29a
Kunena 1.0.10

A quick Google search shows that it has problems working with Kunena. Especially if you had K1.5 installed and then downgraded to one of the stable version. Downgrading to 1.0.9 seems to fix things. 1.0.10 has no fix.

Seems to me this is a GroupJive bug and not Kunena.
