   hello..
   I probably spoiled my installation.
   I uploaded a plugin that was incomplete, and activated it. When I tried to open wp-admin/plugins.php or wp-admin/plugin-install.php, it prompted me to download the files instead. So I deleted the plugin -- and wordpress told be that it deactivated the plugin as it doesnt exist.
   Now each time I upload a plugin, it does not open plugins.php but prompts me to download it. Also, plugin-install.php never opens (always prompts for download)

   Update:
   plugins.php opens okay now.
   And.. plugin-install.php opened this morning. But it had this error at the end:
   Warning: http_build_query() expects at most 2 parameters, 3 given in /home/www/blog.sayakbanerjee.com/wp-includes/http.php on line 248

   So I opened up http.php and found this code:
   $r['body'] = http_build_query($r['body'], null, '&');

   And replaced this with this (in order to have 2 args):
   $r['body'] = http_build_query($r['body'], '&');

   So well, that again made plugin-install.php disappear with the "Download this file" syndrome.
   I changed the code back, while plugin-install.php isn't back again.

   So in a nutshell:
   1. I have akismet and hello dolly plugins in my wp-content/plugins folder. Not the faulty sociable plugin anymore.

   2. Everything in my dashboard works fine, except for plugin-install.php (Install new plugins). That means I cannot have more plugins but only the default ones.

   Getting the exact same error:

   http_build_query() expects at most 2 parameters, 3 given in ... wp-includes/http.php on line 248

   What's weird is that I have a recent, fresh WordPress install with no plugins whatsoever. So I think this is a WordPress bug -- not something you (or I) did.

   If I figure out the problem I will post back.

   thanks,

   That doesn't make any sense, because http_build_query takes THREE parameters, not two. See here: http://www.php.net/http_build_query

   The function is also defined in wp-includes/compat.php for those peoplee running older php versions.

   I might be mistaken but I found that in version 5.1.2 of PHP the arg_separator parameter was added. I'm running 5.0.4 - I have the function, but not the third parameter. So I'm getting the same error.

   My web server was upgraded to the 5.0.3 version of PHP and I got that warning. I had the server reverted back to PHP Version 4.3.11 and there is no warning and I can install plugins. I also have no warning message and proper function while using PHP Version 5.2.8.

   having same error when in plugins_install page if doing anything that needs a search... ( okay on Start page)..

   Warning: http_build_query() expects at most 2 parameters, 3 given in /home/..../wp-includes/http.php on line 251

   Everything was fine before ! the last plugin I activated was WASSUP so I deactivated but the problem still there. I did upgrade my php version from 4+ to 5.02 two days ago but I think (as far as I recall) I did not have this error afterwards!

   Okay, I did another upgrade on my php version to 5.2 and all works fine now - the error disappeared on all plugin-install pges and I installed new plugin with no problem !
