Im receiving this error :

The rewriting does not seem to be working. This may be because you have not configured your server correctly, but may be a false error if your community is not generally accessible. Check friendly URLs are working, and if they are not, ensure you have configured your server correctly or contact your hosting provider or server administrator for assistance.

The forum also breaks when I enable "rewrite urls"

Im being told I need this to work in order for zapier to work--can anyone please help?

If rewriting is not working, you need to follow the instructions given in the text there. If you are sure you only have the default htaccess in place, you need to contact your hosting provider as mentioned
