Can't write into post window with Themia

Hello,

I have two identical sites, one in English, one in Spanish.
http://es.metalesm5.com/
http://metalesm5.com/

My client has admin access and writes the posts. He could write the posts in English, but not into the Spanish post window. He has been writing the Spanish into the English visual window and then copy the code from the text window, then paste to the code window of the Spanish. Not a happy client.

Now he cannot even write in the English. I have been able to post into the Spanish visual window from two different computers, but I cannot upload media to the posts. (see separate thread same day as this.)

I can write and post media into the English visual window.

The version is 2.1.8.

Please help me work this out. My client is getting angry and I understand why.

Thank you,
Carroll Burritt
