plugin-install.php returns "unknown error"

[Corey6986]

When going to add another plugin, I clicked on Plugin-->Add New. I searched for RSS and received the "unknown error" I hit back, and tried clicking on a popular tag same error.

At the frontpage (​http://www.jcoreydavis.com/wp-admin/) with the various plugin suggestions in the bottom left, when clicking on the install button only, same error.

I tried posting at the forums, google search, and searching through the various bugs prior to submitting a ticket.

Sounds like a HTTP Transport issue.

• Manually install ​http://wordpress.org/extend/plugins/core-control/
• Activate it
• Head into the "Core Control" menu item, check the "HTTP" Module, hit save changes
• Open the HTTP Tab (Menu along the top), and paste the results from that page here

Chances are, Which ever is currently the default may have an issue on your setup, Click Test on the transports marked as default and see if that gives an error message. You can also try Disabling the primary transports and then trying the plugins page again, It'll tell us if its the problem with the HTTP api or something else.

These are the things I got from running that plugin.

Hm.. I need to add in POST testing too..

Try disabling the Curl module.. Given that Fsockopen and Streams are not available, That generally tends to point towards PHP having very little functionality available, Curl seems to have problems on -some- hosts like that

[Corey6986]

It is working again now. Thank you for your help. Any idea why it worked before, then stopped working?

[Denis-de-Bernardy]

possibly network timeouts or the likes. close as worksforme?

[DD32]

Yep. sounds like a network routing or server glitch.
