Serialization error

[Matthew]

Hello,

I recently put together a website in Sitefinity (3.6) on one or our development servers. Everything worked fine, but when I transferred it to our client's hosting it is giving me a serialization error. In particular, this occurs when I go to edit a page and it somehow has set Overlay back as default (although I used Custom). Nothing on the page is editable. When I try to change it back to Custom I get this error:

Server Error in '/' Application.

Version Information: Microsoft .NET Framework Version:2.0.50727.4206; ASP.NET Version:2.0.50727.4209


The site is on a Rackspace cloud server. 

I'm lost as to what is causing this. Any help would be very much appreciated.

Thanks,

Matt

Well, 

I changed this in the web.config file:

<httpRuntime maxRequestLength="1000000" executionTimeout="1000"/>

to

<httpRuntime maxRequestLength="51200"/>

back to the default.

Flushed my DNS and it is working perfectly now.

Correction: The above did not fix the issue.

This is very strange. It goes away and comes back.

Hi Matthew,

Could you check whether you are running a build for .NET 3.5 on a server that uses ASP.NET 2.0. Currently your application pool uses .NET 2.0.

Kind regards,

Where could I check this and upgrade it? I'm guessing in the config file, but where exactly?

[Matthew]

Also, the server is supposed to have support for ASP.NET 2.0 and 3.5

Hi Matthew,

Here is a KB that you can use to check the exact version and its build number.

Best wishes,

Thanks. Here are the results:

Build that is returning the error:

3.7.2136.3        .NET 3.5

An existing webpage on the server using Sitefinity that is working properly:

3.6.1936.3        .NET 2.0


Unfortunately I'm new to the hosting (rackspace cloud) and somewhat new to Sitefinity. What are some steps I could use to fix this?

[Matthew]

Would it be helpful if I posted the web.config minus sensitive information?

It seems as though the 3.5 framework is being declared.

[Matthew]

Well I figured out why nothing was editable in overlay mode.

My contentplaceholders had 'whitespace'.

<asp:contentplaceholder blahblahblah </asp:contentplaceholder>

I had to remove the closing tags and replace with:

<asp:contentplaceholder blahblahbla />

But I still cannot switch from overlay edit mode to classic edit mode without getting the serialization error.

Is there something wrong with a script here or something?

Can I disable overlay mode somehow?

[Matthew]

Maybe the best bet is just to disable overlay mode.

Is there a way to do this in the web.config?

Hi Matthew,

You can try setting the page editor mode to classic from web.config:

<cms defaultProvider="Sitefinity" pageExtension=".aspx" projectName="kb" disabled="false" pageEditorUIMode="Classic">

All the best,
