  • Ticket #33498 – Description

    initial v1  
    22I'm running WordPress on Windows through Webmatrix and IIS Express 8.5 and FastCGI.

    4 This function has a bug that appears only on windows due to its different path formatting and causes the web.config to not be writable on PHP 5.5 (error from DOMDocument::load).

    6 WordPress runs addslashes on all $_SERVER/$_GET/$_POST variables which places a burden to remember to stripslashes before using any variable from it.

    8 The get_home_path() function does not do this before using $_SERVER['SCRIPT_FILENAME']. This doesn't cause a problem on Linux because the path format is not modified by addslashes, so it works by coincidence.

    16 Now, PHP on windows is very tolerant of such paths, but some APIs such as DOMDocument::load (test on PHP 5.5) returns an error and logs that it wasn't able to open the file. This is used by WordPress to save the web.config file when it detects IIS.

    1818I have attached a patch that fixes this against WordPress 4.3, but I have seen this in 4.2 as well (didn't test with older).
