For a small percentage of users, the ACLs (permissions) for the /blogs/ directory must be reset in order for the Blogs at Penn State to post entries properly. You will only need to do this if you have activated your Penn State Personal Web space, but receive a directory permissions error.
This will change all settings for all directories back to the default settings. Please allow 15-30 minutes for processing.
If you need to to set custom ACLs, please post a message to blogs@psu.edu
If the above steps do not fix your problem you may need to recreate your www folder. Please see http://kb.its.psu.edu/psu-all/hd/deletedwwwfolder for steps to take. Note that between steps 1 and 2 you'll also need to create a folder called "blogs" within the www folder.
