For whom it’s interesting, you can download patched by me Gengo for WordPress 2.3.x here.

The patch is still be not stable, because code of Gengo is quite complex, therefore it’s not trivial task to fix it, if you are not owner of code. Any way plese post me about any problems there and I will try to fix as far as I will have time for it.

Also I’d like to notice that patch was made without try to keep backward capability with earlier version of WordPress. It was “dirty” hack, purpose of which was only to make it working with my WordPress (v2.3.2). Any way you can post me about any problems.

And finally of course thanks a lot to author of this very well plugin.
