Unable to upload custom content to the new Modstore

On Thursday, May 28, 2026, from approximately 18:07 to 18:57 (UTC), some customers experienced issues uploading custom content to the new ModStore in KnowBe4 Security Awareness Training (KSAT).

This issue was caused by an update to the new ModStore that disabled the language selection field in the “Add Translation” upload step, preventing customers from completing that required part of the upload process. To resolve this issue, our engineering team identified the recent deployment responsible for the defect, corrected it, and deployed the update to production. KSAT returned to normal performance by 18:57 (UTC).

To prevent this type of issue in the future, we are improving test coverage for the affected upload flow and adding automated checks to catch similar issues before they reach production.

No data loss occurred as a result of this issue.
