I found the solution:
change line 36 and 37 inside front-end-upload.php to:
define( 'FEU_DESTINATION_DIR', ABSPATH . '/wp-content/blogs.dir/' . $blog_id .'/files/iti_feu_uploads/' );
define( 'FEU_DESTINATION_URL', get_bloginfo( 'url' ) . '/wp-content/blogs.dir/' . $blog_id .'/files/iti_feu_uploads/' );
Hi Markus, thank you for following up, I’ll be sure to include that fix in an upcoming release!
Your welcome!
Just another question: did you add the multisite-code into the pro-version? And has the pro-version a lang-file?
Thanks!
Markus
Hi Markus,
The update has not been made to the Pro version (yet) but will be within the next couple of days. The Pro version is set up for localization but I’m planning to make a more detailed run through that within the next week or so.
Just wanted to follow up on this and indicate the fix has been applied to both the free and Pro version. Marking as resolved.
