If you host a WordPress blog on Dreamhost and just switched to Dreamhost PS, you’re probably going to run into an issue where you suddenly can’t upload media to your blog. When you upload an image to embed in a post, you’ll probably get an error message that looks something like this:
Unable to create directory. Is its parent directory writable by the server?
The fix for this is very, very simple. When you switched over to DreamhostPS, your blog’s default upload directory changed. Go to Settings -> Miscellaneous, which will open the page you see in the image directly below.
If you have a typical WordPress install (and chances are good that you do), what you see written in my “Store uploads in this folder” field is what should be in yours. The default is ‘wp-content/uploads’ and if you see some other weird thing there, chances are you need to change it back to the default, unless you’ve personally decided to change it to something else in the past. In which case, change it to what you’ve decided to use as your default.
If that doesn’t take care of the problem for you… uh, find someone else to troubleshoot it with you. ;) I’m not an expert or anything. This is just the fix that worked for me and many others.
