So I am getting an exception on an Umbraco 7 instance on windows shared hosting. It seems like after an arbitrary amount of time an issue crops up with the Lucene Index (whose API I do not call directly) and the application goes into a state of error until I refresh the app pool. Any help would be greatly appreciated.

Azure websites uses a remote file system which can cause some havoc with Lucene and we've seen this error quite a few times. I can only assume then that Godaddy also use a remote file server for their IIS websites.
Basically the solution is to run your Umbraco lucene indexes on local temp asp.net storage. In the latest versions of Umbraco (7.2.8+) this functionality is built into the core and you would use the LocalOnly configuration flag for both your indexers and searchers, for example:
<add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
supportUnpublished="true"
supportProtected="true"
analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"
useTempStorage="LocalOnly"/>
<add name="InternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"
useTempStorage="LocalOnly"/>
If you are using old versions of Umbraco you can use a custom library called TempStorage: https://github.com/Shazwazza/UmbracoExamine.TempStorage
This issue has been logged here: http://issues.umbraco.org/issue/U4-3222 but most of the discussion and solution is here: https://our.umbraco.org/forum/getting-started/installing-umbraco/20999-Disable-Lucene-Examine#comment-228320

For a client of ours we have an MVC action which returns PDF files. The following code is the logic to return the FileResult.
public FileResult DownloadAbsFile(string id)
{
String path = GetPathNameByID(id);
if (System.IO.File.Exists(path))
{
byte[] fileBytes = System.IO.File.ReadAllBytes(path);
string fileName = System.IO.Path.GetFileName(path);
return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Pdf, fileName);
}
else
{
return null;
}
}
When I request a PDF file using the right URL most of the time there is no problem. However certain users get an error. The error is puzzling me for quite some time. The error I get is as follows.

On the specific line in the cshtml it tries to access the PageTitle in the ViewBag, which wasn't set. This value is never set, so I get this. But what I do not get is why it is trying to render the view in the first place.
Can anybody help me with this?
I am trying to render a partial view in Umbraco. I have a BaseLayout.cshtml,Homepage.cshtml,BaseLayoutViewModel,HomepageViewModel
This is my BaseLayout View
#inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.BaseLayoutViewModel>
#{
Layout = null;
}
<!DOCTYPE html>
<html lang="en-gb">
<head>
</head>
<body>
#Html.Action("GetPrimaryNavbar", "PrimaryNavbar", Model) //This is there the site throws an error.
#RenderBody()
</body>
</html>
This is my BaseLayout Model. Homepage model inherits from base layout.
public class BaseLayoutViewModel : PublishedContentModel
{
public BaseLayoutViewModel(IPublishedContent content) : base(content)
{
}
public string PageTitle => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageTitle);
public string PageDescription => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageDescription);
public string NavigationName => this.GetPropertyValue<string>(FieldNames.BaseLayout.NavigationName);
}
My PrimaryNavbar Partial view is:
#inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.PrimaryNavbarViewModel>
<header>
<ul>
<li>
</li
</ul>
</header>
And the controller for the PrimaryNavbar is:
public class PrimaryNavbarController : SurfaceController
{
[ChildActionOnly]
public ActionResult GetPrimaryNavbar(RenderModel model)
{
//var primaryNavbarViewModel = new PrimaryNavbarViewModel(model.Content);
return PartialView("PrimaryNavbar");//, primaryNavbarViewModel);
}
}

I cant understand why I am getting "No parameterless constructor defined for this object." Can someone help me on this?
Thanks
To solve the issue you need to send the model like this:
#Html.Action("GetPrimaryNavbar", "PrimaryNavbar", new { model = Model })
Following an earlier post, I'm implementing this YouTube Video Picker in Sitecore - this has involved creating a custom Field Type (YouTubeVideoField). the control itself works no problem but when trying to get the video on the page (#Html.Sitecore().Field("YouTube Video")) I get the following error. Any ideas?

Any ideas?
Thanks!

EDIT: So I'm reading through the Glass Mapper tutorials - do i need to create a custom data handler?
You probably need to implement a custom data handler. If you want to use the supplied custom field see these examples:

Everytime I do a commit and deploy(Publish) to Azure using MVC 4 or 5 in Visual Studio 2012 to my Azure Website which uses Azure SQL for my datasource (not sure what info is pertinent here). I get an Error when Visual Studio pulls up my website in the browser to test it.
Now the error below is what I get until I manually go back into Visual Studio and upload the Root Web.Config file. Which should have just been uploaded anyways. But once I upload that again by itself the errors go away.
Here is the error:
Error:
Format of the initialization string does not conform to specification starting at index 0.
Source Error:
Line 12: </div>
Line 13: </div>
Line 14: #Html.Action("Appraisers", "Partials")
Line 15: </div>
Line 16: <!-- End div class="row" -->
I can't post the entire stack trace here, I'm having problems doing so, but here are the first few lines from each error in the trace:

Sorry about all of that, but I wanted to make sure I gave as much info about the problem as possible.
That error is typically an indication that your connection string in your web.config is not formatted correctly.
Are you doing any transforms of your web.config as part of deployment (e.g. changing the connection string on Release build)?
I have a site with a navigation menu that contains links to various pages. In the menu's ASPX view, we make a call to a model method. The model method executes the authorization filter for each action in a hard-coded list, and the results are used to decide what links to render.
This has worked fine in the past, and still does for most of our users. Unfortunately, a user is now frequently getting errors like the one shown below. The quick summary is that we're getting a NullReferenceException when calling the IsAjaxRequest() method on the request while rendering the view (via code in a custom authorization filter).
The error doesn't occur every time this page is rendered, and I've only been able to personally recreate it once. It has been a persistent issue for one of our users for at least a week now.
I'm guessing that the HttpRequest is being invalidated at some point before the view processing begins, but I can't find anything to confirm that. Could this be the problem? Or could it be caused by one of the servers between the user and our web server, like a proxy or our firewall?

The problem was caused by the RequestContext being stored in a static variable in the model. When multiple users used the site, there was a chance that the HttpRequest would be reassigned and disposed by one user while another user's request was in progress.
The disposed HttpRequest was the cause of this error, and other similar ones that we're no longer seeing since deploying this fix.
