Unexpected issues around images not displaying, Mod rewrite error

[Matt Cohen]

Hi there, I am getting server 500 errors when trying to display images on my site.

Here is my web.config file

<?xml version="1.0" encoding="UTF-8"?>

                <remove extension=".php" />

            </profiles>

        </caching>

    </system.webServer>

</configuration>

When I remove this section I get the imagees to display but all the sub directories on the site don't display?

      <add input="{URL}" pattern="^/~?[-_.a-zA-Z0-9/]*$" ignoreCase="false" />

                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />

                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />

                        <add input="{REQUEST_FILENAME}" pattern="(favicon\.ico|robots\.txt)" ignoreCase="false" negate="true" />

                        <add input="{URL}" pattern="\.(gif|jpg|png|ico)$" negate="true" />

 

Any ideas. Running PW on IIS 7 on Windows Server 2008 r2.

Maybe this thread could help? https://processwire.com/talk/topic/268-processwire-on-windows72008-server-with-iis-webserver/

What do you mean by "trying to display images on my site"? I'm using your (original) web.config and it's working, at least I don't get 500, (2008 R2, IIS 7.5). Configure Failed Request Tracing, maybe you can see something in the logs?
