Re: upgrade error
I got this on an IIS server too.
The simple fix seemed to be to cut and paste the following into the new config file after the line “$bb_table_prefix = ‘bb_’; // Only letters, numbers and underscores please!” …
// If your bbPress URL is http://bbpress.example.com/forums/ , the examples would be correct.
// Adjust the domain and path to suit your actual URL.
// Just the domain name; no directories or path. There should be no trailing slash here.
// There should be both a leading and trailing slash here. ‘/’ is fine if the site is in root.
$bb->path = ‘/’; // Example: ‘/forums/’
Once the upgrade was done, I could go back and remove the lines and it all seemed to work.
