Real Staging servers use the same (or closest possible) setup as Live. </p><p>2. Computers are automatons - if their behaviour changes it's because they were told to change. If the software doesn't differentiate between environments or yesterday then something else changed - so the poor server setup is <em>not</em> the only difference, and your first step is to identify which other differences exist.</p> <br /><p><i>> If I put a copy into a subdirectory on the live site, it works, cookies and all.</i> </p><p>Check your version control history for what changes were made - sounds possible that somebody may have set/changed the path attribute of the cookies. Then again, you would have spotted that when you compared the actual cookies for the different environments to check for differences, so maybe it's something else.</p><div class="edit_text">EDITED: 25 Jul 2015 15:45 by BOUGHTONP</div> </div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=41539.2&return_msg=41539.1" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="41539.2"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a41539_3"></a><div class="message" id="message_41539_3"> <div class="message_header"> <div class="message_from"> From: CHYRON (DSMITHHFX)<span class="message_time">25 Jul 2015 16:03</span> <div class="clearer"></div> </div><div class="message_to">To: Peter (BOUGHTONP) <span><span class="image post_read" title="Read: 25 Jul 2015 20:52"></span></span> <span class="message_count">3 of 10</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=41539.3">41539.3</a> In reply to <a href="lmessages.php?webtag=DEFAULT&msg=41539.1#a41539_2" target="_self">41539.2</a></div> <div class="message_body"> I did make some edits to the javascript yesterday unrelated to the cookies stuffs.
