When creating a project in WorldServer (including Transport) the project creation fails. The error Cannot create project group appears briefly after clicking Finish in Transport or in the Modern User Interface.

In the Classic/Legacy UI, an internal error will appear. When clicking the Error Details, the stack trace appears. The same stack trace can also be found in the ws-legacy.log.

The relevant part of the error is 
 

ERROR https-openssl-apr-443-exec-11 com.idiominc.ws: Encountered error during servlet execution: com.idiominc.wssdk.WSRuntimeException: Cannot create project group: Cannot create project group

1- Go to Management > Business Rule Linkage > Project Types and open the Project Type used to create the project
2- In the Project Type details, go to the Linguistic Tools tab
3- In the Machine Translation Configuration section, you will find the reference to the MT Adapter. For example:



4- Now go to Management > Linguistic Tool Setup > Machine Translation Configurations
5- Find the configuration mentioned in the Project Type and click on it to open it
6- You will see that the MT configuration does not open correctly and that an error similar to the one written in the log file during project creation appears:



Fixing the Machine Translation certificate issue will fix the problem. The Machine Translation Configuration should then be visible. The project creation using a Project Type that points to that Machine Translation configuration will work correctly.
