I need to change my weblogs language to “English”.
I am refering to the article: http://en.support.wordpress.com/language-settings/ which allegedly was “Last modified: July 16, 2012”.
I only looked for this option in v.3.4 forward and I cannot find it.
It’s also absent in v.3.5 beta 1. I initially installed and still use the German locale.
Thus:
1). Were these simple drop-down menus removed from more recent versions? Because I can find neither of the two.
2). Could my webhoster be at fault somehow? They offered the “WP One-Click-Install” option, which I thought shouldn’t hurt things – I guess I was wrong…
3). Could be my German locale at fault, i.e. maybe only the “international” or “English” version has this toggle, but not any of the downloadable locales? Just a guess.
I am aware of the fact that I can change the language of WP manually, but first I need a clarification what happened to the above feature since July 16th this year.
No, they were never there. The link you posted is for WordPress.com hosted blogs, not self-hosted WordPress.org software.
