I'm getting the same error when trying to clone an item as I am getting when I try to add a manufacturer.
1. Clone item #1 and it's works just fine. Now I have item #2.
2. I want to clone item #1 again, as item #3 is just a different color.
3. When I press the clone icon, I go to an error message (screenshot attached), but it creates the clone anyway.
4. This is exactly what happens when trying to add a manufacturer to the system, but that happens on the first attempt.
I posted this in the old issues area also, I couldn't get into the new one.
This is a generic AbanteCart page if some system or code error happens.
Once you see this error it is a good idea to go to error log in admin and grab last few lines with the error.
This helps to identify the problem faster.
I tried your steps and it is all good for me. Never got any error
Thanks, I'll look at the log, but it is erratic. Seems to be fine now, maybe my server?
