WordPress Upgrade Error Solved!

Around here at ETHODE we use WordPress quite often.  Matter of fact it usually accounts for 80% of our websites that are not custom coded.  Recently we ran into an issue where we were trying to upgrade a blog for a customer.  We installed the blog using Fantastico and then wanted to upgrade to the latest version using the nice automatic upgrade utility.  We thought originally the issue was permissions.

Could not copy file.: /public_html/wp-admin/css/theme-editor.dev.css
Installation Failed

The error message was quite frustrating.. We tried different FTP users, changed (chmod) permissions and still no dice.  Finally I decided to check out the server FTP configuration and compare it against our shared hosting environment and WALA!  On our shared servers we use ProFTP and on this dedicated server we were using Pure-FTP.  For what ever reason, Pure-FTP doesn't sit well with Fantastico installations of WordPress..

I changed the ftp server over to ProFTP and boom, upgrade was successful!

Happy Coding!
