I have had to re-install WP half a dozen times this week. I install Twenty eleven, make a child which always fails one way or another. Sometimes it says success but doesnt appear. Other times it gives can't write errors.
I go to ftp and give /themes and or /uploads public write which usually ends with the blog going blank, and no themes shown in ADMIN except in the activated window a no name nothing with a WIDGETS link. And then I cant install any themes at all.
I try deleting the themes in FTP but nothing fixes it so I assume WP is broke and re install it. This goes on and on in an never ending sad pity potty song, The Child Theme Blues...
*I am first steps setting up a WP site behind the scenes to replace my Serendipity site of 5 years. I have learned enough .html .css .php and unmanaged dedicated server crap to get me by for some time now.
