I'm using a single install of WP 3.8 on a self hosted server.
When going to Akismet to input the API key the following message is displayed: "There was a problem connecting to the Akismet server. Please check your server configuration."
On trying to save the API key this message is shown: "The key you entered could not be verified because a connection to akismet.com could not be established. Please check your server configuration."
I have tried a default WP theme and the problem persists. It also persists when every other plugin is deactivated.
I copy and pasted the WP files I am using to a new server form an old server, as is described here: http://codex.wordpress.org/Moving_WordPress. The old server was a shared hosting setup, whereas the new one is a VM.
On my WP Admin dashboard under WordPress News the following message is displayed: "RSS Error: WP HTTP Error: couldn't connect to host".
Additionally when I search for new plugins from with the WP admin panel I get this message: "An unexpected error occurred. Something may be wrong with WordPress.org or this server’s configuration. If you continue to have problems, please try the support forums."
I also had issues with getting media files uploaded until I changed the owner of the uploads folder to www-data.
I strongly expect I have set up the server wrong in some way as I have not done any of this before. However, I haven't a clue what I have done wrong.
Any help, especially that in lay man's terms, is greatly appreciated.
