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.
