Update Translations module to use Clay Tablet version 4.1.2.
Due to changes in the Clay Tablet connector communication interface, the Progress Sitefinity CMS Translations module updated its communication protocol accordingly. Clay Tablet connector changes take effect on July 13, 2018.
To ensure uninterrupted translation service through Clay Tablet software, it is required that all Sitefinity customers utilizing the Translations module upgrade their installations prior to July 13, 2018 to the latest available Hotfix or Internal build for their main Sitefinity version. The existing version of Progress Sitefinity CMS Translations module will not be able to submit or retrieve Clay Tablet translation jobs starting July 13, 2018
For more information about available Hotfixes and Internal builds, please refer to this KB article Update Translations module to use Clay Tablet version 4.1.2
