How do you interpret that log? I see some warnings about your functions.php file, but I don't see any information about the $time variables logged. This indicates that either
1. you added the error log statements in a way that they are not being executed or are broken
2. or the notices are preventing the error log statements from working somehow.
First, fix the notices. On line 756, use isset() to check if the post variable is set before you try to use it. Then look at this code:
add_action('cred_save_data_934', 'success_for_form_with_id_934',10,2);
function success_for_form_with_id_934($post_id, $form_data){
if($form_data[id] == '146' || $form_data[id] == '305') {
Since you added the action specifically to form ID 934, the form id conditional is not required here. In fact it is preventing the code beneath it from being executed because the form ID will never be 146 or 305.
