WordPress 4.6 - request_filesystem_credentials issue #4

Closed polevaultweb closed 8 years ago

polevaultweb commented 8 years ago

Whenever I do anything in my site, like add a post I get redirected to a whitescreen asking for FTP credentials.

This only happens in 4.6, possibly related to https://core.trac.wordpress.org/changeset/38138 or https://core.trac.wordpress.org/changeset/38167

Error log output:

Thanks! I'll fix this in a couple of days, because I'm moving houses at the moment. You're welcome to submit a PR in the meantime.

Cheers @tillkruss - wouldn't know where to start :(

I just changed the output buffering. Could you try and replace your existing nginx-cache.php file with this new one: https://github.com/tillkruss/Nginx-FastCGI-Cache/blob/master/nginx-cache.php

... and let me know if that solves the issue.

@tillkruss YES, fixed - thanks!
