      Description

      When creating feedback in Moodle 1.9.3, the Tab "Show responses" fails silently without any error, even with debug set to ALL.

      When clicking on "Show response" tab, page header as well page tabs are shown, but the HTML source is stopped at the following line:

      ....omissis.....

      <!-- END OF HEADER -->
      <div id="content">

      <div class="tabtree">
      <ul class="tabrow0">
      <li class="first"><a href="http://mydomain.tld/mod/feedback/view.php?id=30716&do_show=view" title="Overview"><span>Overview</span></a> </li>

        Hi Andrea,

        it seems to be a memory_limit problem. If you have a large number of users on your site so it can appear.
        Please have a look at this issue: MDL-17005
        (http://tracker.moodle.org/browse/MDL-17005)

        Hi Andreas,
        thank you for your answer. I used the workaround as per MDL-17005 and the problem disappeared. Sites has about 40k users.

        Also tested leaving Authenticated user role to default and overriding only in courses, and also worked.

        Unsure if the best default is allowing Authenticated users to submit feedback, or let Admin/Teachers override the role when needed. 1.9 also added the front page default role, so probably it could be safer to change the default permission: what do you think ?

        FWIW, the fix of changing "mod/feedback:complete" to 'not set' in MDL-17005 worked for us.
