Support » Fixing WordPress » Plugin upload error: "Please select a file"

  • Hi!

    I’ve just managed to get my site up and running that I’m doing via Google’s App Engine.

    I’m actually trying to install the app engine optimisation plugin right now but WordPress isn’t letting me upload anything. It keeps going to an error page with the simple message “Please select a file”, which is thoroughly perplexing.

    I’m hoping this isn’t a problem with my Google cloud SQL service, because that would be a pain in the arse.

    I’m wondering if anyone has any ideas? I would greatly appreciate it!

  • What happens when you search for a plugin and then try to install it and not trying to upload one?

    Hi graphical_force

    It asks me for FTP credentials instead, which I’m also having trouble with :/ Namely my hostname, FTP username and password, which I’ve been trying to guess for a while now but to no avail 🙁

    Have you asked your hosting company for those? They are not the same as your WP login.

    Your saying you are being asked that through the WordPress admin screen?

    It always comes out with something like Failed to connect to FTP Server localhost:21

    Have you spoke with your hosting company like WPyogi asked?

    @graphical_force yes, I believe so (sorry for the not very helpful answer!)

    @wpyogi I’m hosting via the Google App Engine, so I might have to ask them as you say. Looking around in the their admin page hasn’t yielded anything useful yet.

    Thanks for the replies btw 🙂 I’ll update with anything I find.

    Installing plugins and themes on a cloud instance doesn’t work because Google App Engine doesn’t allow write access to the area where your app files are stored. That’s why you get the peculiar error message “Please select a file”.

    Google provides the (as of this writing) experimental Google Cloud Storage API for storing and accessing files that aren’t part of your deployed app (see

    Short of rewriting WordPress to support Google Cloud Storage under the hood, you might be able to get around this by installing the plugins and themes locally before you upload your WordPress instance to the cloud.
