What version of Umbraco are you running?

[vascozorrinho]

7.7.9

well, that should work, but obviously it does not - investigating

@vascozorrinho Is it possibe for you to zip up your bin folder and drop it here?

[nul800sebastiaan]

@vascozorrinho Never mind, we found it! Fixing now.

[zpqrtbnk]

New version 3.0.10 has been uploaded to NuGet and is being indexed now.

Sorry about it!
