SharePoint doesn't work as intended

Opening a web part page in maintenance mode

Reading Time: 3 minutes. 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 dificult, right? :)  Posts Related to “Opening a web part page in maintenance mode”:SharePoint-Teams -integration using a tabSharePoint Localization – […]

SharePoint vs. Anonymous

Troubleshooting: Anonymous access on a public SharePoint site collection failing

Reading Time: 4 minutes. Ah, everyone’s favorite, classic topic! 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. Symptoms A lot of different ways to hit your head on this one. In any case, your on-premises SharePoint doesn’t allow anonymous access to a site where you are trying to allow it. Most typically, they’ll just encounter 401 error when […]

Let me explain SharePoint

Don’t remove the root web of your classic SharePoint Site Collection!

Reading Time: 5 minutes. A quick heads-up – if you remove the root site (or RootWeb, like it’s called in the code) of your classic SharePoint Site Collection, that’s going to cause you some grey hairs. It might even, in some rare cases, be unrecoverable! Why? Whereas you can always restore a normal site from the site collection recycle bin, the root site you can’t. You actually can’t access the recycle bin after removing the root site, nor can you make magic happen with PowerShell commandlets anymore. The Recycle […]

Using PowerShell to modify anonymous access permissions on SharePoint On-Premises

Reading Time: 2 minutes. 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’s 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. […]

Malformed web.config causing a Parser Error

“Server Error in ‘/’ Application” or “Parser Error” – it’s actually a malformed web.config killing your ASP.NET-application or SharePoint

Reading Time: 2 minutes. 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 […]
