WildMagic, that worked great for me.
But I’m concerned.. will I keep having this problem?
I upgraded, everything went fine and then the 500 server errors with the .htaccess bit.
I figured out the .htaccess yesterday, deleted it, and then realized how my permalinks were broken, so I had to go into every post (omg) and resave.
Today it spontaneously happened again.
Fortunately I checked here and did what you said, and I didn’t have to resave each one manually, but I’m wondering, will this happen again?
Does anyone know if this is a WP bug that can be fixed?
And I renamed my .htaccess file and then took out the www in the general options and voila.
I couldn’t delete the original post, so I thought I’d update it with what worked for me.
I’m having this problem and the conical change isn’t helping and I can’t access my admin to shut down the problem in the options.
Any ideas?
