title: Silex deployement IIS
body: <p>i'm working on a Silex project and i have this error 500 that i cant figureout how to fix it.</p>
  
  <p>the project is located on a shared drive (a file server) behind another server with IIS and php 5.5.
  I dont have any prob on my local server.</p>
  
  <p>The error:</p>
  
  <pre><code>string(2710) "An exception has been thrown during the rendering of a template ("Invalid resource provided: "1.2"; Errors: [WARNING 1549] failed to load external entity "file://///PASE-CFG-PP1/IIS_CONTENT/MYPROJECT/vendor/symfony/translation/Loader/schema/dic/xliff-core/xml.xsd" (in n/a - line 0, column 0)
