Hello,

I'm using: 

{{if request.module == 'forums' && request.controller == 'topic'}}
{{$topic = \IPS\forums\Topic::loadAndCheckPerms( \IPS\Request::i()->id );}}
{{$forumid = $topic->container()->id;}} forum-{$forumid}
{{endif}}

in globalTemplate to get the forum ID for styling purposes. It does its job, however, if users view topics they lack access to, they're presented with a: 

[[Template core/front/global/globalTemplate is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]

which logs as a template error: 

OutOfRangeException::0

 

This seems wrong: 

forum-{$forumid}

 

Or do you print it directly in template?

Yes, to <body class="">

You're using loadAndCheckPerms() so naturally if the user does not have access then they will run into an error. You can try something like this instead: 

{{ try{ $forumId = \IPS\forums\Forum::loadAndCheckPerms( \IPS\Request::i()->id )->_id; } catch( \OutOfRangeException $e ){ $forumId = 0; } }}

I tried: 

{{if request.module == 'forums' && request.controller == 'topic'}}
{{$topic = \IPS\forums\Topic::loadAndCheckPerms( \IPS\Request::i()->id );}}
{{ try{ $forumId = $topic->container()->id; } catch( \OutOfRangeException $e ){ $forumId = 0; } }}
 forum-{$forumId}
{{endif}}

but it's still giving unauthorized users a template error.

The line calling loadAndCheckPerms() needs to be wrapped in the try/catch, as that's where the error is thrown. 

{{if request.module == 'forums' && request.controller == 'topic'}}
{{ try{ $forumId = \IPS\forums\Topic::loadAndCheckPerms( \IPS\Request::i()->id )->container()->id; } catch( \OutOfRangeException $e ){ $forumId = 0; } }}
 forum-{$forumId}
{{endif}}
