Hi Jan,

Could you post the rest of the Exception message? Specifically the stack-trace... then we can pinpoint what the root cause might be.

Thanks, Lee.

Server Error in '/' Application.

Hmm... still not much to go on - not your fault, meaning the exception message isn't very detailed.

Check your Web.config file, see if the Medium Trust settings have been applied.

In your <appSettings> section, set the "umbracoUseMediumTrust" value to "true".

<add key="umbracoUseMediumTrust" value="true" />

Then inside the <system.web> section, add:

<trust level="Medium" originUrl=".*" />

.. then fingers crossed!

Cheers, Lee.

Hi Lee,

I have already switched the umbracoMediumTrust keyvalue to true:

<addkey="umbracoUseMediumTrust"value="true"/>

My hosting provider does'nt allow to set the trust level value.

Is there something going on with reflection when publishing a page? The save action is going ok with no errors. What is the difference in events when saving or publishing? One thing is the writing to the umbraco.config file.

Greetings, JK

It shouldn't be an issue writing to the "umbraco.config", as I'm sure there'd be more complaints. (Personally I've been doing some dev work on upcoming 4.8 in Medium trust exclusively, which can publish fine).

Are you using any custom data-types, or 3rd-party packages? (or have upgraded any other components? e.g. Examine 1.4)

Cheers, Lee.

No just the standard installation of umbraco 4.7.2. Is it possible to mark any section in the web.config with requirepermission="false" to see more of the actual error? I've already done the client dependancy section.

Greetings, JK

Try adding it to the <section>s for "Examine" and "ExamineLuceneIndexSets".

(If that doesn't work... I'm pretty much out of ideas - sorry)

Cheers, Lee.

Is was the log4net section.

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false"/>

Fixed the problem.

Greetings, JK

Great! Glad that you found the cause. :-)

Cheers, Lee.

Thanx for the support Lee.

Greetings, JK

is working on a reply...
