Regular usage of the “Add Plugin” function, just like always. As a matter of fact, this screen didn’t display any errors the day before.
Overview / Popular tab displays the error: " An unexpected error occurred. Something may be wrong with ClassicPress.net or this server’s configuration. If you continue to have problems, please try the support forums."
Also, searches using the search form return nothing, ie. the loading animation is being displayed … and then the above mentioned error message appears.
I aint have the faintest clue why this happened. Out of the blue, access to the cp.net API seems to be blocked. Even disabling the only plugin I yesterday installed changed nothing, so its definitelly gotta be something going wrong, either from my install to cp.net or from cp.net to the wp.org API.
I am fetching Query Monitor for further analysis.
