Same error message after trying to activate a new install of WooCommerce.
Guess I’ll seek an alternative!
I went to the server and deleted the plugin, so now I have access to the site again — a bit concerned about trying to install WooCommerce once more!
Podz, adding that line to .htaccess worked. You’re my hero! Thanks a lot!!
Podz, I have a similar problem. I have a new WP install on an Apache server with mod_rewrite working. I was able to add a blank .htaccess file and get WP to update the Permalink structure. I also added “Options +Followsymlinks” at the top of the .htaccess file. But the Permalinks still do not work. Where do I find the apache http.conf file, so that I can add your DirectoryIndex line to it?
