Good day! When I try to add new plugin or theme then well-known text appears :
"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."
After disabling all plugins same result.
The site is under construction, I'm using theme created with Artisteer 4.
I installed WP maybe 4 months ago and there was not such problem during that time. How can we test what can it be in my case? Thank you very much!
