....Cause
There are problems with user settings as this only occurs for a particular user in Confluence.
Resolution
Run the following query in database to check if it returns any rows. This OS_PROPERTYENTRY table stores all of the user settings:
SELECT * FROM OS_PROPERTYENTRY where ENTITY_NAME='CWD_<username>';If it returns one or more rows, this means that some settings are not set to default. So we would like to set them to default by clearing these rows and renaming them to something else:
UPDATE OS_PROPERTYENTRY SET ENTITY_NAME='CWD_<username>_backup' WHERE ENTITY_NAME='CWD_<username>';- Restart Confluence and see if the problem persists
To restore the changes that are made above, just run the following query and restart Confluence afterwards
UPDATE OS_PROPERTYENTRY SET ENTITY_NAME='CWD_<username>' WHERE ENTITY_NAME='CWD_<username>_backup';
