Unfortunately from the provided PHP Fatal Error, it appears that the issue is not caused by the server environment but a development issue with the code of your website. We can advise you to contact a developer or the support team of Mahara to receive further assistance on the matter as development tasks are out of the scope of our expertise.

==================END REPLY FROM HOSTS.

I'm using Mahara Version 

16.04.1

Can't seem to find anything about this on here as yet. And can't really find my way around the Bug Tracker but searched there too. 

Any thoughts please, wizened ones of the mahara community??

Much thanks in advance.

Hi Rob,

This is an issue that has just been found, see the bug report:

https://bugs.launchpad.net/mahara/+bug/1591304

There is a fix for it, see patch:

https://reviews.mahara.org/#/c/6595/

Basically one needs to find this line of code in lib/view.php

return !$view->get('template') && !in_array($this->type, $unthemable_types);

And change it to

return !$this->get('template') && !in_array($this->type, $unthemable_types);

Cheers

Hi Robert

Much thanks for your solution, which worked. 

(it also affected 'Edit this Page' btw)

Thanks for the option of the line of code to edit.  Turned out to be much simpler to do in the end.

The git/patch thing proved too much for me to get my head around, leading me to download whole Megs of material, which I do not know how to integrate with the installation. So the simple code edit was (eventually) achieved. 

Cheers again

Robert
