Upgrade went ok but pressing on order I got a null error but now I seem to get the below error and nothing I do works. Has anybody got an idea where to look for a solution

Hello, 

Based on your screenshot it looks like the "keyword" field in the "order" table in the database is receiving the value "null" and causing the error. You should check the database again or intervene in the "getOrderSources" function in the \classes\ConnectionSource.php file.

Please backup data before making changes to the code or database to avoid unnecessary problems.

I hope this will be helpful for you.

Best regards.
