Recovering from a WSOD related to hierarchical select module I was messing around with the hierarchical select module (trying to create an exposed filter that would use the hierarchical select interface) I got some strange AJAX related error and then tried to cancel out of what I was doing.  After doing so, when ever I try and edit this view I get the White Screen of Death. I went to MAMP server PHP log files and found this error:


  [02-Feb-2012 15:58:10] PHP Fatal error:  Call to undefined function _hierarchical_select_setup_js() in /Applications/MAMP/htdocs/sites/all/modules/custom/hierarchical_select/modules/hs_taxonomy_views_handler_filter_term_node_tid.inc on line 26


Since I can't get back to my view I don't seem to have any way to remove this broken exposed filter.  Any way out or did I just lose this whole view?
The _hierarchical_select_setup_js() function is defined in the hierarchical_select.module so this is one of those "it should work" situations.  Since it isn't, a quick workaround would be to copy it out of there and into, oh, say, your template.php file, wrapped in a "if !function_exists()" so it doesn't WSOD when it does :)
