Visual Studio 2010 publish failing with error Unable to add XYZ to the Web site. Access is denied (550).

I started receiving this error when trying to publish through Visual Studio 2010:

Unable to add XYZ to the Web site. Access is denied (550).

The reason being someone had manually FTP-ed files to the website and they had read-only set to true.

Resolution:

Make the folders/files not read-only - easy :)

Using EMs for font size

Can you set

body

{

font-size: 62.5%

}

This means that we can use em’s

So 22px will be 2.2ems, 33px will be 3.3px, this is useful for responsive design.

Umbraco 404 custom error page not working on staging/production server

My custom 404 error page in Umbraco was working locally but not when I deployed to staging/production. The reason was explained very nicely here: StackOverflow.

So basically you can add the following to your deployed web.config under :

Duplicate trees in Umbraco CMS after uninstalling uComponents

I freaked out when I uninstalled uComponents and discovered that all content, media, settings, and developer trees had all been duplicated. After cleaning my solution and removing all dlls in the bin directory the trees returned to normal.

Umbraco packages throws error installedPackages.config is denied

This was happening on IIS7.5 and the error message said I should add ASPNET account to the security of the file. Instead (as I was using ApplicationPoolIdentity) I removed the Read-Only flag on the packages folder and this fixed my problem.

Umbraco drop down list prevalues using razor

Here is a great link that converts the drop down list datatype prevalues into a Dictionary. Hope this helps someone else out there:

Umbraco "Oops...the installer can't connect to the repository!"

I was getting this error on a new Umbraco 4.11.1 installation but only when viewing the site from IIS7 and not when running the site from VS 2010. This also made my packages folder in Umbraco developer tab empty.

I had all the correct permissions on my website folder but it was still failing to display when visiting my dev URL setup in IIS.

The solution was to add the same user/group for the website folder to the C:\Windows\Temp folder. Umbraco was failing permissions trying to access this folder.

Hope this helps someone.
