Unable to login after update 1.5.2 -> 1.5.5


  • Restarted IIS. When I browse to the UI, I get a login page with message below "Could Not Determine Database Version" and the log shows:

    2023-06-29 16:09:33,756 [7] ERROR Toems_ApiCalls.ApiRequest Response Data Was Null For Resource: Version/GetAllVersionInfo
    2023-06-29 16:09:33,774 [7] ERROR Toems_ApiCalls.ApiRequest Response Data Was Null For Resource: Setting/CheckMfaEnabled/
    

    Could it be related to that?


  • Probably, if doesn't know the current version it can't update. What if you manually go to http://localhost/dbupdate.aspx


  • Getting this:
    f13f682c-a4cc-4c81-bdb7-16a15a84c7bd-image.png


  • You used the update installer and not the full installer correct?


  • Correct. Theopenem.Update-1.5.5.msi.
    I believe however that I have seen the message "Could Not Determine Database Version" appear even on 1.5.2, but because everything was working, I haven't chased it.


  • We would need to hop into heidisql to look at the version table.

  • Not sure why this is happening. You could try manually updating the database. In HeidiSQL select the theopenem database then select the query tab, paste in this script to go from 1.5.2 to 1.5.5. Then execute the script.

  • Thank you, that ran without issues, however unfortunately the problem still persists:

  • @theopenem_admin - Don't chase this further - I believe this is a remnant from my failed attempt at upgrading MariaDB - https://forum.theopenem.com/topic/466/unable-to-to-login-system-invalidcastexception-object-cannot-be-cast-from-dbnull-to-other-types .
    Back then I had to downgrade and because of all the database enconding and collation changes I had to manually edit my MariaDB 10.11 backup so I can have it restored under 10.5. I belive this is now causing my database schema, although working to be out of sync with the model/schema in your coude - hense 'The model backing the context has changed since the database was created.'. What I did was go back to a pre-MariaDB upgrade backup, had that restored, it properly updated to 1.5.5. and now I can login fine. Thanks for your help anyway!
