WordPress 4.4 upgrade breaks FTP capability within WordPress. Installed WordPress 4.3.1_1 from pkg ; used WordPress built-in upgrade feature to install new core, also attempted installing WordPress 4.4 from new core downloaded from WordPress.org. Neither installation could create or write files (via WordPress FTP implementation; couldn't delete/install themes, plug-ins or re-install core using the built-in WordPress interface (FTP through PHP calls). After creating a bug ticket with WordPress they tracked it down to an issue in their FTP implementation that was recently upgraded with the 4.4 release. They have a work around on their nightly 4.4.1 build, but we discovered another solution was to install php56-ftp-5.6.14 from the pkg repository as this isn't a dependency in 4.3.1_1 but I guess should be flagged as one going forward with WordPress 4.4. For more info on this please visit https://core.trac.wordpress.org/ticket/35026 Thanks.
Fixed with 205400.
