No backend acces after online update 1.7.3 to 2.5.0 !

[rbuelund]

I just tried to update my Joomla 1.7.3 site via the update manager to Joomla 2.5.0. After update i got a white screen with this error message at top: "Fatal error: Using $this when not in object context in /..../libraries/joomla/plugin/plugin.php on line 103"

I could not use backend anymore !!??

I have reestablished the site throug a backup.

Could it have anything to do with "jSecure Authentication" which I use to secure backend access ??

same problem here..

But it happend when i updatet from 1.7.3 > 1.7.4

Do you use danish translation as well?
If i put it back to English in site language my site is live again, but still have some errors in the backend no matter what i do.

I know that this dosent help your problem but maybe you could an idea about what went wrong, cause im so lost?

My problem was related to jSecure which doesn't support 2.5 yet.
