SharePoint 2010 – The old, reliable, legacy portal solution by Microsoft. It was fun when it came out, but it was a completely different world back then.
These posts handle the on-premises installations and their issues.
Can’t access a web part page because of a broken web part? Yeah, that’s a classic issue – and it’s nicely ported into Modern world, too! In these cases, web part page maintenance mode comes in handy! There’s a query parameter available for accessing it. For whatever reasons, it’s different for Classic and Modern mode, though. Why make things easy if you can make them difficult, right? :) Posts Related to “Opening a web part page in maintenance mode”:SharePoint Home, Hub, Sites, Start… What?SharePoint Localization…Continue reading Opening a web part page in maintenance mode
Debugging SharePoint On-Premises configuration issues is the best thing since sliced bread, right? This post is about allowing/enabling Anonymous Access to a site collection – a simple configuration, that “simply works” like once every ten times you try it.
This blog post describes how set the SharePoint’s ULS level to “Extra Verbose” (VerboseEx) using PowerShell. This is not possible using the browser UI, so some POSH magic is required! Luckily, it’s quite straightforward, but to avoid filling your hard drive(s) with huge log files, you should reset the level when you’re done debugging! Description of the solution By default, ULS logging is somewhat non-detailed. This means that a lot of data that could be used to debug issues is omitted. The UI cannot be…Continue reading Using PowerShell to set ULS logging level to “extra verbose” to catch all the events in the logs
This post is about managing Anonymous Access on a SharePoint site (SPWeb) using PowerShell commandlets. It’s often a lot more feasible and even easier than using the browser interface! In some cases, it’s borderline impossible to avoid it anyway – since accessing the GUI switch might not be possible. Description Assume you have a site collection that you have published to the whole world. You’ll have anonymous access enabled at both web application and site collection levels, and configured permissions at the root web -level.…Continue reading Using PowerShell to modify anonymous access permissions on SharePoint On-Premises
Have you ever run into this, a very non-descriptive and weird SharePoint error message “Cannot uninstall the LanguagePack 0 because it is not deployed”? You could encounter it while running some PowerShell scripts – most typically when trying to update a wsp solution. I have, and luckily often easily solved! Symptoms Assume you’re trying to install, update or uninstall a SharePoint solution (.wsp package) using PowerShell-commands Install-SPSolution, Update-SPSolution, or Uninstall-SPSolution (respectively). The operation fails with the following (or similar) error: Error: Cannot uninstall the LanguagePack 0…Continue reading Powershell Error: Cannot uninstall the LanguagePack 0 because it is not deployed.
This post describes how to resolve a kind of cryptic and oddly misdescriptive error message about Parser Error on your ASP.NET application or (an On-Premises) SharePoint site. I ran into this after deploying wsp-packages to a SharePoint farm, but you can apparently get this on ASP.NET MVC sites, too. The error doesn’t actually tell you what’s wrong, so figuring it out took a while. Hopefully it’ll help you, though! Symptoms: Parser Error from a random-looking location Once you navigate to your web- or SharePoint site, you only…Continue reading “Server Error in ‘/’ Application” or “Parser Error” – it’s actually a malformed web.config killing your ASP.NET-application or SharePoint
This post is about solving the issue with Visual Studio 2010 failing to show the design view of an .aspx-page. Luckily, it’s an easy and pretty classical fix. Symptoms While trying to view or edit an aspx-page in design mode in Visual Studio 2010, the window is just plain empty and there’s little you can do about it – selecting view markup or hitting F7 may not do anything and restarting the Visual Studio doesn’t help. Solution The Design view requires connection to the SharePoint…Continue reading Visual Studio 2010 fails to show the design view of an aspx-page
Sometimes – pretty often in the good old on-premises world, actually – you’ll need to have a copy of all the packages that are deployed to a certain farm. So – how to download all of the deployed farm solutions (essentially, cabinet files renamed to .wsp) from a farm? Luckily, it’s quite easy! Solution To download all deployed farm solutions (wsp-packages) from a SharePoint farm is pretty simple using PowerShell. No need to download individual packages through cumbersome interfaces! You don’t even have to open…Continue reading Quickest way to download all the wsp-packages in a SharePoint farm
This post describes a few different ways of fixing the error “The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.” one can get encounter this issue at least when trying to package/publish a SharePoint solution, web site or an Azure Webjob. Symptoms Visual Studio throws the following error when packaging a SharePoint solution to a .wsp file when deploying or publishing your web…Continue reading Fixing the error: “The specified path, file name, or both are too long.

In this post, I describe how you can figure out if IE11 (Internet Explorer 11) has jumped in the compatibility mode. You run into this requirement every now and then, when trying to figure out some SharePoint browser compatibility mess-up. This is quite frequent, because in compatibility mode IE does its best to screw up your CSS. Compatibility view now and before Microsoft has been pretty keen on introducing new ways to handle browser compatibility and make IE behave in even stranger ways that it…Continue reading Identifying IE11 compatibility mode in SharePoint
This post describes the (probably) easiest and most straightforward way of creating a new Thread in your SharePoint (or any other .NET) server-side/desktop code. Solution Let’s face it – one should not create new Threads lightly when developing SharePoint solutions, but sometimes it’s difficult to avoid. Or sometimes it’s just the simplest way to get around weird framework limitations.

At times you may need to allow unsafe updates for SPWeb objects to get your code to run. This, in SharePoint’s C# full-trust code, is done by setting SPWeb.AllowUnsafeUpdates to true. However, as this is an exception to security settings, you should generally avoid it. When you can’t, it’s a good practice to limit the change to as small a scope as possible. This is true even though the setting is only persisted for the duration of the request (unless the SPWeb object was gotten…Continue reading How to properly use SPWeb.AllowUnsafeUpdates
This post is about fixing one of the most annoyingly unspecific errors you can get when activating (Feature Framework) features on SharePoint – “File not found”. Whatever that might mean, right? Problem Ugh. A plain and simple “File not found” is one of the more annoying errors one can stumble upon when trying to activate a feature. It usually gets thrown at you quite quickly after hitting the activation button on your feature management page – and it’ll look somewhat like below: There are quite…Continue reading “File not found”error when trying to activate a custom feature on SharePoint
This post is about a small programmatic workaround to creating new SPFields for SPLists in SharePoint with human-readable internal names. This is mainly a usability improvement for your editors (and doesn’t change your life that much), but at the very least they will probably appreciate it! In short, I’ll show you how to avoid SharePoint’s dirty encoding (like replacing a space with “_x0020_”). This appliesto when you’re using server-side code to generate fields. Problem: non-readable internal names for SharePoint list fields When you create a…Continue reading Programmatically creating readable internal names for new SharePoint fields
This post describes how to fix Windows Authentication on a SharePoint server that is failing on other local addresses other than localhost. Symptoms You get the standard Windows/Basic Authentication prompt when accessing your SharePoint site, but the site won’t accept your credentials when you are accessing the site using an address like http://website. However, using an address like http://localhost works fine (but of course may cause other problems). You also get event log entries like this (most likely in System -category): The program w3wp.exe, with the…Continue reading Windows Authentication fails on SharePoint for all hostnames (other than localhost)
