Can’t read image folder after upgrate to 1.5.0.1

After upgrad, when insert image to description, the programm can’t read the Media folder any more, and always shows SQL data error.
can Any one solve this ?

es I think there is a small issue with one of the files probably Tree.php.  When it looks for the image directories, sub directories and files it looks for the table “ _core_directory_storage” but with the most recent upgrade this table seems not to be included.  I don’t know whether this is intentional or not as this table does not seem to be used!

Whatever, the net result is that any sub-directories which are created do not appear.

I have tried adding _core_directory_storage to all my DBs and it seems to work so if you back up your database you could run

SET FOREIGN_KEY_CHECKS=0;

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
