This is the error I get on one of the web pages I run.

Under CUSTOMERS > ORDERS

Right next to the customers name , order total and Status I get this message:

Fatal error: Call to undefined function zen_get_orders_comments() in /home/content/r/c/h/XXXXX/html/XXXXX/orders.php on line 871

I compared orders.php file with another web that runs just fine and I am able to edit, delete, invoice, packing slip on the other web page.

I used a Code Compare software, and both files on both webpages are identical.

What is up with that???

I see many people here are reloading the file, but what is the point if the code is identical.???

Is it possible that code err is some where else?
