Thread:Project:Support desk/Upload Warning - Could not create directory "public/9/95".

After I tried to install an extension, somehow I am no longer able to upload any images.

If I try to upload an image in the `Special page´ Upload File. When I click on 'Upload file' I receive this message in the top of my screen:

Warning: wfMkdirParents: failed to mkdir "/home/xxxxxxxxxx/domains/findhomeremedies.net/public_html/wiki/images/9/95" mode 511 in /home/xxxxxxxxxx/domains/findhomeremedies.net/public_html/wiki/includes/GlobalFunctions.php on line 2532

And I get a message telling me:

Upload Warning - Could not create directory "public/9/95".

Who can help me out here?
