The exception happens if the system cannot find any page templates (I made some changes so in the next version there will be a more appropriate exception message).
You should check the server log for additional details. Could be something wrong with the configuration ("/App_Data/Composite/Composite.config" file) or with the templates itself.

We have been investing heavily in 2sxc for a client with a large site. We've built a number of custom apps and added quite a few content types to the default Content App.
About a month ago we started seeing slowness when saving front end data and saving ContentTypes in the Content App (but only there). The site would take 20 - 30 seconds to save. Now it's gotten worse and started throwing exceptions intermittently. Save is no faster than 30 seconds. At other times it's 60 seconds. Intermittently the content fails to save and we get the error message and exceptions listed below.
However we have no problems saving content within other apps like the Blog app and our custom apps. Performance there is fine. Also 2sxc modules in general seem to render fine for front end users.
We are running 2sxc 8.4.5 on DNN 7.4.2.
Here is the initial Error Message:

Thanks to Raphael Müller this issue has been solved. He suggested rebuilding indexes on the database. Once that was done the content saves went from 45 seconds plus with timeouts down to 1.5 seconds. Boy is my face red. Oh well live and learn. The lesson is simple: Make sure your database has a maintenance plan that includes the rebuilding of indexes.
Here are some helpful links for those who might encounter this issue.
Here is a script to rebuild all indexes in a database. In theory the script should not lock your database or website but anything is possible so it's best to execute off hours. It took 5 minutes to run on my DNN database which is around 2.5 Gb. https://gallery.technet.microsoft.com/scriptcenter/Script-for-rebuilding-all-8d079754
Michelle Ufford's Index Defrag Script is an advanced solution. I've run it on my stage server successfully and it seems to be well received by the community. http://sqlfool.com/2011/06/index-defrag-script-v4-1/
Here is a helpful discussion on how often to schedule your index rebuilds. How Often should the indexes be re-build in sql-server DB?
I'm working on a DNN 6 installation and for some reason all of my admin (even as a super user) menus/options are no longer accessible.
Every time I try to access a simple menu like Admin > Site Settings I get this error:

Any hints as to what could be happening?
Thank you!
Looking at this, it looks like you are using a custom Skin Object called "ArtMenuSkinObject" and it is having trouble.
You will want to check with the developer of the skin object.
I am using DNN module 5.6.1, and i created a custom module using Devxpress controls,
It is installing in dnn site, but when i try to add the module in a page, i getting the following Error,
A critical error has occurred.

Can any one please help me to fix this error
This is a very generic error. You may want to look through your Event Log to see if there are other errors that occur at the same time more related to your specific module. Debugging the module to see what exception is coming from your module can also be helpful, rather than trying to unwind these stack traces that, more than likely, are going to be wild goose chases.
What often happens with DNN is that a module fails while loading, and then other parts of the skin and container fail because the module was never fully setup correctly. These are the NullReferenceException errors that you're seeing.
bdukes said the main things I would guess anyway keep the following problem in mind, too.
another reason for this problem could be a specific servertag used in a dnnwrapper.
for example if you are using telerik wrapper from dotnetnuke but placing telerik controls in this wrappers without having a refference on the telerik assambly.
example:
<dnncontrols:datepicker>
<calendar>
<SpecialDays>
<telerik:calendarDays />
</SpecialDays>
</calendar>
</dnncontrols:datepicker>
If you are doing this you will get a nullreference as you got. This Problem drove me crazy to find it so I decided to post it here.
I hope this will help you.
But at first I would suggest the way bdukes described (this is the normal way to go).
best regards
I get this error when I load a page that uses a specific skin (GeneralContentPage). I have deleted the ascx page and parsed the skins again but still have the same error. Would appreciate any input!

Thanks

If skin is set at portal level. go to site settings and change the skin to default (minimal extropy)
If skin is ste at tab level, you have to go to Host > Sql and reset the skin src of the tab.
In which situation following error occurs?
Unable to cast object of type 'MyType' to type 'Castle.Proxies.MyType'.
UPDATE:
I got this error message while binding MyType.FindAllByProperty("col1", "foo"); to a GridView (exactly a Telerik's one: RadGrid). This error is not occuring every time, just sometimes. Here is markup of my grid:
<telerik:RadGrid ID="grdList" runat="server" AutoGenerateColumns="false" OnNeedDataSource="grdList_NeedDataSource"
OnUpdateCommand="grdList_UpdateCommand" AllowAutomaticUpdates="True" OnItemUpdated="grdList_ItemUpdated"
AllowMultiRowEdit="true">
<MasterTableView EditMode="InPlace" DataKeyNames="PageInRole_id" AllowAutomaticUpdates="true">
<Columns>
<telerik:GridBoundColumn DataField="ContainerPage.PageTitle" HeaderText="Title" UniqueName="ContainerPage.PageTitle"
ReadOnly="true" />
</Columns>
</MasterTableView>
</telerik:RadGrid>

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927
This exception probably comes from the code trying to re-attach a proxied/lazy-loading entity to a session. The most likely API call to throw this exception with a newer NHibernate (I don't have problem with 2.1 but I do have problems with latest) is Session.Lock(obj, LockMode.None).
If the programmer of this component first evicts the entity from the ISession and then re-loads it (perhaps cached?) into another one by id, or performs ISession.Update this problem should go away until the NHibernate team has figured out the underlying problem.
I had a similar problem with EntityFramework 6.0.
I had migrated from an old version of EntityFramework that did not use proxies and had some code that created and attached new instances of the entity via new MyEntity();.
My solution was to use dbContext.MyEntity.Create(); instead so I only work with proxies. Something similar should be available for NHibernate if I recall correctly.
My error was:
Unable to cast object of type 'MyProject.MyEntity' to type
'System.Data.Entity.DynamicProxies.MyEntity_849E94C98E5E543D6DF5245252144E3EAC00131F811886276B6ABD991719D232'
We ran into the same issue with RadGrid having AutomaticInserts. After inserting an item it throw InvalidCastException: Unable to cast object of type 'MyDbModel.Role' to type 'System.Data.Entity.DynamicProxies.Role_...' in DataBind() at Rebind().
The issue was gone after I adapted the DataBinding to have an OrderBy().
