I'm getting the same error. Could it be related to http://world.episerver.com/Modules/Forum/Pages/thread.aspx?id=82638&pageIndex=1
I'm also getting errors in code(but they do compile). As an example the x in x.RelesWithReadAcces is underlined with red and the text "Cannot convert instance argument type 'namespace.FactPage' to 'EPiServer.Security.IContentSecurable'
var allResults = SearchClient.Instance.Search<FactPage>().For(searchString)
.Filter(x => x.RolesWithReadAccess().Match("Everyone"))
.Select(x => new SearchHit
{
I have the same problem. I'm not getting any errors from code and everything else works just fine.
Edit: And I just upgraded from 7.1.2 where everything was working with Find also.
We have just released a fix for this bug.
It is available for Download in the Nuget feed now.
I recently updated to EPiServer 7.6 and wanted to try out EpiServer Find.
While installing and putting the information in web.config I compiled (works fine) and started my project.
I got in to EPiServer CMS but when trying to access the Find section I get this error:
Parser Error Message: Value cannot be null.
