Hi Simon,

It seems that you need to turn on HTTP Compression, Try to make sure that your settings is like this in your web.config file

<system.webServer>
    <urlCompression doStaticCompression="false" doDynamicCompression="false"/>
    <!-- your definitions here-->
</system.webServer>

Or perhaps it could be a good idea to get in touch with your hosting provider smarterasp.net. support, to be sure that everything is okay to run your Umbraco installation.

Hope this helps,

Hi Simon

Unless you have changed the settings Dennis mentions above yourself they should already be set to false by default.

You should get in touch with support to ensure that everything it setup properly in their end.

I assume that the site is working fine locally on your own machine? How did you do the deploy? And what exact version of Umbraco 7 are you using?

Hi Jan,

I am suing Umbraco 7.2.1. I have deployed the site via web deploy but first I deployed it locally and then uploaded via FTP, because some errors where occuring when trying to deploy directly to the server, that umbraco/xslt/web.config cannot be open source, altough I have changed the Build action to None :/

As Jan said, Dennis, I have already have that code snipper in the web.config

 <urlCompression doStaticCompression="false" doDynamicCompression="false" dynamicCompressionBeforeCache="false" />

I don't know exactly why this error is occuring because locally is running fine. What do you mean that by "get in touch with your hosting provider smarterasp.net. support, to be sure that everything is okay to run your Umbraco installation." Dennis?

The CMS is working fine  and content is their as well. But frontend, web page is not available.

Thank you. Appreciate any help, since I cannot make it run properly.

Kind Regards

Hi Simon,

I mean that you should try to contact to your hosting provider smarterasp.net support department to ensure that everything it is setup as it should be to running Umbraco on your webhotel.

Try to see this thread from stackoverflow perhaps it can help you http://stackoverflow.com/questions/14039804/error-330-neterr-content-decoding-failed

Hi Dennis,

They told me that server settings are set correctly. :/

Hi All,

The problem was solved. 

Umbraco web.config has compression set to false, for both static and dynamic, and the smarterasp.net site configuration was set as HTTP compression set to true.

So I turned it OFF and it works.

But, I don't know if I should have a compression or not?

Appreciate any feedback.

Thank you.

Kind Regards

Hi,

One more. I would appreicate if you guide me how to deploy the site directly to the hosting, becuase it is telling me either that Install.web.config or umbraco/xslt/web.config cannot be opened. 

But both the option to change the Build action to None, does not solve the issue. Also, if I try to delete both config files, they will be genereated again, and error will pop up again.

Appreciate any guide.

thanks guys.

Kind Regards

Hi Simon,

The problem is come from HTTP compression. I have ever experienced same error above. Please contact your hosting provider to enable HTTP compression. It should be fix your problem

I just had the same error.

My web.config already had the urlCompression snippet mentioned like this:

<location path="umbraco">
   <system.webServer>
      <urlCompression doStaticCompression="false" doDynamicCompression="false" dynamicCompressionBeforeCache="false" />
   </system.webServer>
</location>
<location path="App_Plugins">
   <system.webServer>
      <urlCompression doStaticCompression="false" doDynamicCompression="false" dynamicCompressionBeforeCache="false" />
   </system.webServer>
</location>

But it needed to be added to the top of the system.webServer section. Once it was in there I was cooking on gas.

I was deploying using Visual Studio's Publish command, not sure if that's in anyway relevant.

Have same problem with the same host-provider.

They said:

It caused by your site already compressed so you don't need to enable our Control Panel http compression , otherwise it will compress twice and decompress only once and show error

The umbraco application can not enabled the http compression.Please consider to not use this function.

What?! May be umbraco compess http by itself?

is working on a reply...
