I all ready found the problem...
The ini file does not contain translation of the name of days, months etc.
I took the en_BR ini file, changed the translation, and it works.
see the working file here:http://www.yaad.org.il/ischool/index.ph ... 11/10/30/-
and the wrong one here:http://ischool.haifa.ac.il/index.php/20 ... 11/10/30/-
I'll be glad to do the full translation to Hebrew, but never did it, and don't know what files need to be changed.
If you'll send me the files (front and back - end)to translate, (from English) I'll send them back to you translated.
Have a nice day
