Error message on most content types

Hi,

Running multisite with latest H5p and with latest libriaries. On most content types when creating them and displaying using the shrotcode we get the following error message:

Warning: copy(/data/httpd/efolio/htdocs/blog/wp-content/blogs.dir/11596/files/h5p/temp/h5p-5881ecd5156c4): failed to open stream: No such file or directory in /data/httpd/efolio/htdocs/blog/wp-content/plugins/h5p/h5p-php-library/h5p-default-storage.class.php on line 144

The content is still created and the object still gets displayed OK. We seem to have ongoing problems with multisite and H5P :(

Any ideas?

Alex
