Upgrade from 22 to beta26 failed

[محروم.كوم]

Hello.

Before I had 5 beta 22 version, tried to update 26 version.
I had an error when I had taken last step that the system is making XML. I guess It is about language pack matter. I had Turkish language pack which is windows1252. But I deleted that from the adminCP.

Anyway I added that language pack, and tried to update again. It failed with the same problem.

Please see screen shots on this link below.

I think DB has garbage value about language pack, please tell which part it is.



And the one more thing,
When I set the Turkish language as default, It change admin CP too. I want to see adminCP with English language.
So I set my account default language as English but it shows Turkish.
How can I use adminCP with English without not changing user page language. __DEFINE_LIKE_SHARE__
