RouterOS 6.20 Upgrade problems

RouterOS General
1

I have an installation with Mikrotik RouterOS running on a PC (x86). That machine run’s Usermanager and hotspot Services.

After the upgrade I have been seeing Script Error Database is not acessible, yet.
When I go to system Disk I do not see the various partitions (web Cache, UserManager etc) on that machine.

I have tried to downgrade to RouterOS 6.19 but does not help.
When I downgrade to RouterOS 6.19 and I try to go to the userman page, I get Error 404: Not Found

Please can you urgently assist as I have a site down.

All support is much appreciated.

I have the same problem, On my RB1100A AH X2, and the RB1100, No Micro SD Card Access at all. Did you figure out a way around this problem, Looks like the update broke it.
