I have following plugins installed on my WP version 3.3.2:
- Admin in English version 1.2
- NextGEN Gallery version 1.9.3
I had these plugins for a long time without any problem but after the latest updates I was unable to upload images to NextGen galleries using its flash upload feature. Then I found out that when I disable the Admin in English plugin, I am able to upload images again. So I think there is a conflict between these two plugins somehow and since NextGen is more important for me right now I am unfortunately disabling the Admin in English plugin.
