Some editors (such as vi) leave droppings, swap files, etc. These files should not be loaded by the autoloaders since they don't match the pattern *.php$

This works perfectly in the catalog (editing a file in includes/functions/extra_functions doesn't break the page), but in the admin side, it fails.

The fix is simple: in admin/includes/init_includes/init_general_funcs.php, line 46, change

if (strstr($zv_file, '.php')) {

to

if (preg_match('/\.php$/', $zv_file) > 0) {
