Issue Summary

Enabling Maintenance Mode + Recovery Mode (as described in Restore Passwords to Recover Admin User Rights results in all login attempts failing, including those for the Recovery Admin user. The error displayed is:
"Something went wrong. Refresh the page and try again."
This effectively makes Confluence entirely inaccessible.

This is reproducible on Data Center: Yes

1. Enable Maintenance Mode in Confluence.
2. Enable Recovery Mode by setting the required property in confluence.cfg.xml as per Atlassian's recovery guide.
3. Restart Confluence.
4. Attempt to log in using the Recovery Admin or any other user (admin or non-admin).

Expected Results

• The generated Recovery Admin user should be able to log in to perform administrative actions.

Actual Results

• All login attempts (including those from the Recovery Admin) fail with the error:
  "Something went wrong. Refresh the page and try again.":
  

Workaround

Disable Maintenance Mode and restore access (Outside the UI):
Option 1:

1. Modify the confluence.cfg.xml file in the Shared Home directory:
   1. From: <property name="access.mode">READ_ONLY</property>
   2. To: <property name="access.mode">READ_WRITE</property>
2. Restart Confluence.

Option 2 (Database) - Take a backup before any modifications:

1. Run the following SQL query:

   SELECT * 
   FROM BANDANA 
   WHERE BANDANACONTEXT = '_GLOBAL' 
   AND BANDANAKEY = 'atlassian.confluence.settings';
   

2. Copy the entire BANDANAVALUE
3. Find <maintenanceBannerMessageOn>true</maintenanceBannerMessageOn>
4. Change it to <maintenanceBannerMessageOn>false</maintenanceBannerMessageOn>
5. Run the following query to update the BANDANAVALUE:

   UPDATE BANDANA 
   SET BANDANAVALUE = '<Paste the entire BANDANAVALUE after the modification>'
   WHERE BANDANACONTEXT = '_GLOBAL' 
   AND BANDANAKEY = 'atlassian.confluence.settings';
   

6. Restart Confluence.
