Hello Laura and Nina,
The tutorial mentioned is the tutorial I used to validate my site:
http://skins.dnncreative.comThe first step is to get DNN to validate without any modules
Then to get your skin to validate
Then to get the various modules to validate.
So far I just followed the tutorial and got the Text / HTML module to validate.
Generally you can fix the validation problems even with just the PA of the module, because in most cases all you need to do is edit the .ascx files.
Generally this would involve chnaging all of the uppercase tags to lowercase and also closing all tags, eg. <br> should be <br />
After following the outlines in the tutorial for getting the Text/HTML module, image module etc to validate, you just apply those techniques to any of the other modules you need to validate. - In most cases you will not need to edit the core code of the module, but you do need to edit the core DNN code to get DotNetNuke to validate.
If you want to find out more about writing code that validates, read this tutorial:
XHTML and best practice coding for skins and modules in DotNetNukeHope this gives you a starting point. - Just remember to do all of these experiments on a localhost installation before trying it on a live website, especially when making changes to the DNN core code. - More than likely it will take you a few attempts to get it right if you are new to DNN.
Thanks,
