Sarah / I'm trying to use this theme for a cilent and it's generating this error: Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, mytheme_add_admin' was given in /home1/webdcmar/public_html/wp-includes/plugin.php on line 395Can you please double-check this and email me if you've corrected for the problem? The old version of Handgloves isn't even upload-able anymore. Just generates a string of errors. Thanks!
