Problem:
Client was getting a blank page, with the following URL /wp-admin/admin.php?ateJobCreationError=102&jobId=225 when trying to translate a piece of content from the translations queue by clicking the 'Translate' button on the right-hand side in the admin area.
Solution:
There was a message in Translation Management about "Site moved or copied". I assumed it to be a staging/test or dev site, so I used "This is a copy of my original site" option, instead of moved to a new site.
