this morning appeared me this error when I try to update the order status:

Someone know how I can solve this?

Please post the OC version. This issue is caused by an installed extension. Contact the extension developer or submit a new service request at site support from the extension Marketplace page to resolved this issue.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.
