no system log, no order list; upgraded from 2.4 to 2.5

Found the problem

When you navigate to certain pages in the admin section, is does a rewrite rule for things like:

https://websitename.com/admin/log/loglist?loglevelid=0&availableloglevels=system.collections.generic.list%601%5bsystem.web.mvc.selectlistitem%5d&log-grid-size=15

to
https://websitename.com/admin/log/list


I used the default rule provided with IIS 7 to make all urls lower case:

                <rule name="LowerCaseRule1" stopProcessing="true">
                    <match url="[A-Z]" ignoreCase="false" />
                    <action type="Redirect" url="{ToLower:{URL}}" />
                </rule>


When I removed this rule from web.config the admin section started working normally.
