WordPress 3.0 Plugin Install/Upgrade Problem “Could Not Create Directory”
Some of you might have noticed that after the WordPress 3.0 upgrade there seems to be some kind of problem with installing/upgrading plugins via FTPS (SSL). I am not sure why this bug happens, but here is a quick fix to get you going.

Could not create directory. /public_html
I am not sure why this bug happens, but here is a quick fix to get you going.
Open FileZilla or whatever FTP client you want to use and navigate to your wp-content directory, check for a updates folder. If you have such a folder delete it and create it again. Now CHMOD it to 777. Try updating or installing new plugins in your WordPress admin. In most cases it works as a charm.


I was getting this error but didn’t have the ‘updates’ folder. I found that the ‘upgrade’ folder had some temporary files still in it so I deleted them. I set the ‘upgrade’ folder to 777 for good measure.
After that my theme upgrade and plugin upgrade worked fine.
