This is why I suggested you look at these submit forms comparing v1.3.8 to v1.3.9 ...
For example, the sidebox for tpl_search.php ... just the change to the code from:
Code:
$content .= zen_draw_form('quick_find', zen_href_link(FILENAME_ADVANCED_SEARCH_RESULT, '', 'NONSSL', false), 'get');
to read:
Code:
$content .= zen_draw_form('quick_find', zen_href_link(FILENAME_ADVANCED_SEARCH_RESULT, '', $request_type, false), 'get');
will submit it as non-secure or secure based on the current page ...
All of the forms can be adjusted in this manner ...
