This patch resolves another issue where saving author meta data could cause an error.
Detailed log
For everyone
- Fixed: Resolved a fatal error after saving a user profile containing custom TSF metadata (such as a Facebook profile link or X handle).
- If you saved your author profile with 5.1.1 active or changed the counter type, you must repopulate these fields. Since the bug was so short-lived and practically an edge-case, we expect no issue here. Also, no social network actually uses these handles.
