The "Validation errors" tab in Translate displays errors in the translation files which are causing publication issues. Once a validation error occurs, project managers should also receive an email notification. 

Common errors and ways how to fix them:

1. Error message: "Either Abstract or Summary section must be translated."
   • Open the link to the affected Phrase project and check whether all segments are fully translated. Once the translation has been updated, trigger the publication process again by changing the status of the document to an earlier status such as "New" and then back to "Completed by provider". 
2. Error message: "Missing or misplaced tag(s) in the translated text."
   • This error message indicates a possible issue with Phrase tags. Open the link to the affected Phrase project and run the QA check in the QA tab at the bottom of the right-hand side panel. Select the errors that you want to look for such as "Tag/Formatting" and click "Run". Clicking on the error will take you to the respective segment where you will be able to fix the issue. Please find further details here. Once the translation has been updated, trigger the publication process again by changing the status of the document to an earlier status such as "New" and then back to "Completed by provider".
