I transferred my site from one server to another. It had WPMU DEV and Hummingbird installed. I went to run to open the DEV Dashboard and it failed to open. I tried to open Hummingbird and it too failed to open. So, I deactivated and removed all WPMU plugins (DEV and Hummingbird) , and re-installed WPMU DEV plugin in hopes a re-install would fix things. I was able to login to the DEV Dashboard but cannot install any other plugins: I am getting an error when I try to install Hummingbird and SmushPro on my website:
"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."
Thoughts on what might be the issue?
