Re: Running gallery module from localhost gives error
When I saw this error I was hoping you would help.
This error looks releated to NeatHtml which is used to prevent cross site scripting attacks. Dean is the author of NeatHtml so he is the best one to help with this.
You can disable NeatHtml in Web.config with:
<add key="UseNeatHtmlForXSSPrevention" value="false" />
That might make your error go away but better to fix the problem than to disable NeatHtml, so please work with Dean and follow any advice he gives.
