When trying to edit a page in Oracle APEX 24.2.11, this error appeared: The Ajax call returned the server error ORA-01403: No data found for getSharedData.
Sometimes the message is this: ORA-30036: Could not extend segment by 8 in undo tablespace 'UNDOTBS1' for getSharedData.
Now I can no longer edit anything. Not even back up my project.
