I ran into a problem with one of the blogs that I manage, there was no way to upgrade a plugin. It just wouldn’t get past the FTP information form. I put the correct FTP information in, and that failed too.
I was out of options, so I went searching and found a plugin called “One Click Plugin Updater“.
This plugin actually saved me a ton of work, and trouble in the future because it has some amazing features. First of which, is that if you have any plugins that need to be upgraded, it will upgrade all of them at the same time. Secondly, it bypasses the craziness that WordPress runs into, which would cause you to have to figure out the FTP form.
All you have to do is put the plugin on your site, activate it, make sure plugins directory is set to the correct permissions, and go.
When you need to update, just hit the button at the top of your admin pages. You don’t even have to go to the plugins page.
