New installation of WP3.01 - no themes or plugins installed at;
1.)Dashboard shows "WP HTTP Error: name lookup timed out" on Incoming Links, WordPress Blog & Other WordPress News.
2.) Plugins / Add New: a search gives "An Unexpected HTTP Error occurred during the API request."
3.) Tools / Import / Install Importer /Blogger - "An Unexpected HTTP Error occurred during the API request."
A repeating log file error e.g.: [23-Aug-2010 18:00:39] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/jowimcon/public_html/photo-blog/wp-includes/class-http.php:1) in /home/jowimcon/public_html/photo-blog/wp-includes/pluggable.php on line 890
That one may have been eliminated when I deleted and replaced all WP files.
So far, I've read all the posts on this problem and;
a - changed 'timeout' in /wp-includes/class-http.php from 5 to 30
b - tried to activate the Core Control plugin but that killed WP
c - file / dir permissions are correct
d - user / group permissions on the server are correct
When none of that helped, I deleted all files (except wp-config) and FTP'd a fresh version in but the problem persists...
The hosting guy is very helpful and he is as perplexed as I am.
Does anyone have any helpful suggestions?
