I normally use Fantastico Deluxe to update wordpress as I am not a techie, however as I noticed my version of wordpress was getting rather out of date I decided to try WordPress' own automatic update facility.
Unfortunately I got this error message:
Could not copy file.: /public_html/blog/wp-admin/css/theme-editor.dev.css
I am not sure what to do next. Do I just wait for Fantastico to catch up or try the automatic update again?
