I just got the same message using 1.7.1. Except mine said line 37.

Site was working fine then all of a sudden i get this..

Any confirmation that this is a bug or a coincidence?? Im gonna have to redo the whole site.

1. Make sure your web server does not have permission to write to the directories and files in Elgg. Do this for security reasons.

2. Copy over a clean copy of the code. Code like this doesn't suddenly break so that code must have been changed.

Wetodid prob wants some funky "grouped" search mechanism.. lolz ;-)

    // search based on tags
    case "search_tags":
        $options = array();
        $options['query'] = "Teenager"; // this will fetch interests marked as "Teenager" lolz
        $options['type'] = "user";
        $options['offset'] = $offset;
        $options['limit'] = $limit;
        $results = trigger_plugin_hook('search', 'tags', $options, array());
        $count = $results['count'];
        $users = $results['entities'];
        $filter_content = elgg_view_entity_list($users, $count, $offset, $limit, false, false, true);
        break;

if he puts this code somewhere and creates a link to it.. he got it 95% done.. yadda yadda yaddda ;-)

   // search based on tags
    case "search_tags":
        $options = array();
        $options['query'] = "Marketing"; // this will fetch interests marked as "Marketing" lolz
        $options['type'] = "user";
        $options['offset'] = $offset;
        $options['limit'] = $limit;
        $results = trigger_plugin_hook('search', 'tags', $options, array());
        $count = $results['count'];
        $users = $results['entities'];
        $filter_content = elgg_view_entity_list($users, $count, $offset, $limit, false, false, true);
        break;

Ty very much, now all I need to do is figure out what and where to do with that code and I'm golden...hehe

lol @ Teenager
