Blank Setup page after downgrade from 10.0 to 9.1

[warface]

Hi there,

Using a VM-50 that has been running fine on 10.0.2 until there was a need to downgrade the VM.

After taking backups then downgrading to the 9.1 feature release, the Setup page in the UI is now blank.

I have tried upgrading/downgrading to various 9.1.x feature releases and committed several different configurations to no effect.

The setup page remains blank no matter what browser or system I access it from.

Is this a know issue and is there any workaround?

Action Taken/Required
-------------------------------------------
- We upgraded the VM firewall to version 10.0.7.
- Uninstalled dlp plugin.
- Downgraded the VM firewall to 9.1.0.
- Checked the Device -> Setup page and setup page loaded up fine.
Any further downgrades should work fine for the setup page as well

Hello @ITD_SAS  even if I dont use panorama to manage my firewalls, can I applicate this command to desinstall the plugin? I have a pair of HA firewalls and did and upgrade to the 10.0.8, but in the tsf I get in the active DLP plugin and this is causing my mismatch an no sync, so i wanted to know if this is useful to delete that plugin.
