I'm trying to upgrade WordPress version of a blog and it fails. I input FTP info (host, user, pass and type) then I get the message:
Unable to locate WordPress Root directory.
This blog is running on Windows 2008 Enterprise host.(If it was up to me, no doubt it would be hosted on a Linux server.) My fisrt thought was that it was happening because the path is
I can't install or upgrade plugins from WordPress admin either. Does it happen because it's hosted on a Windows server?
I've set WP_DEBUG to true on wp-config.php and tried to upgrade again. The following message repeated several times:
PHP Notice: Undefined variable: b in E:\Home\<host_username>\Web\wordpress\wp-admin\includes\class-wp-filesystem-ftpext.php on line 334
PHP Notice: Undefined variable: b in E:\Home\<host_username>\Web\wordpress\wp-admin\includes\class-wp-filesystem-ftpext.php on line 337
I've checked the wp-admin\includes\file class-wp-filesystem-ftpext.php to see what might be wrong on lines 334 and 337. Below is the code from line 334 to 337:
if ( $b['islink'] ) $b['name'] = preg_replace( '/(\s*->\s*.*)$/', '', $b['name'] ); return &b;
The blog in question only has Akismet 2.5.8 active. Jetpack 2.3.3 is there, but it's not active. It's a new blog, started from WP 3.5.2. So definitely plugins must not be the cause of the problem.
And of course I know that I can upgrade WordPress uploading files of the new version over FTP. My point is I want to solve the issue of not being able to upgrade WordPress and install/upgrade plugins from its own admin.
Any ideas on how to fix it?
