hello,
At a parent web.config we had:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<handlers accessPolicy="Read, Execute, Script" />
<httpErrors errorMode="DetailedLocalOnly" />
</system.webServer>
</configuration>
we changed the value to:
<httpErrors errorMode="Detailed" />
And it worked, the errors are now displayed on the client browser and not only on the server.
Got here trough the search:
customErrors mode="Off" IIS 7 asp 1.1 500
Regards
