I get this strict warning when I ask a question in faq_ask module: Strict warning: Only variables should be passed by reference in faq_ask_node_insert(). The PHP file is faq_ask module and the path to it's location is: sites\all\modules\faq_ask\faq_ask.module). The code looks like this:

  // Are we notifying the expert(s)?
   if (variable_get('faq_ask_notify',FALSE)) {
   // Use only the first term entered in the correct vocabulary.
   $term = taxonomy_term_load(array_shift(array_keys($terms)));

The code is found around line 466 in the faq_ask module file. I've been looking around for a solution to this probleme but I dont know much PHP, I just started focusing on the subject, and the fact is; I'll probabely never be a expert.

Welcome to Drupal Answers :) Unfortunately this isn't the place to report bugs with contributed modules. The module issue queue would be the best place to report it; please feel free to copy the code from the answer below as a suggested fix – Clive♦ Nov 6 '12 at 0:18

You're getting the warning because array_shift() takes its first argument by reference, and to pass a variable by reference it needs to be defined. At the moment you're passing the evaluation of a function call (array_keys($terms)), which isn't a variable.

You can remove the warning by changing your code to:

$tids = array_keys($terms);
$term = taxonomy_term_load(array_shift($tids));

The answer is correct, but that is, I think, a contrib module and this should reported as a bug, not asked here. We can't answer a bug away :) – Berdir Nov 6 '12 at 0:14
@Berdir Oops yes you're right, I didn't notice it was a contrib module :) – Clive♦ Nov 6 '12 at 0:16
Sorry if I made someone do something they're not supposed to do, but I'm all new to this and I've been searching for a week to find a solution to this warning. I will report this as a bug asap, and by the way; THANKYOU for helping me with this. – Jon Vikan Nov 6 '12 at 8:44
