OK, I've solved the problem that I had in post 889. If you look at the code on the page you will see there was a comma missing at the end of the list of items, i.e. 'stylecache', 'utt_store_act', etc.
The code below shows the correction:
PHP Code:
// add default special templates
$specialtemplates = array_merge(array(
'options',
'cron',
'forumcache',
'usergroupcache',
'stylecache',
'utt_store_act',
'arcadesettings'
),
