Together with help from Kunena and JoomDev we determined that the issue is in the template we have in use. We were unable, however, to reproduce the issue and/or determine its cause.
For us it's minor since super users will not log in to the frontend of the forum. Case closed.
Thanks. I'll ask the the other parties. It kinda makes sense, seeing that their code is mentioned in the error message.
I'll let you know of their findings. It may safe other people coming across this issue some time.
We are setting up Kunena ahead of a migration. When I log in with my site administrator account, I receive the following error:
Rendering Error in layout Widget/Module: Call to a member function cachedCompile() on null. Please enable debug mode for more information.
With debugging turned on, as suggested, the full error message is:
Rendering Error in layout Widget/Module: Call to a member function cachedCompile() on null in /var/www/vhosts/transalpclub.nl/kunena.transalpclub.nl/plugins/system/helix3/core/helix3.php on line 774

self::getInstance()->addCSS($css . '.css', $attribs);
default.php line 25 (-->):
--> echo $this->subLayout('Widget/Module')->set('position', 'kunena_top');
The if statement is inside a block starting with:
<div id="kunena" class="layout <?php echo $this->options->get('pageclass_sfx'); ?>">
The module is published in the kunena_top position.
I haven't got a clue where to start looking. With a normal, non-privileged, account the module works fine.
Any help would be appreciated.
