Re: Problem with webhosting Medium trust

If you moved the site from another machine I would delete all rows from the mp_IndexingQueue table as it may have had the index path from your old machine there.

See also Moving an Installation of mojoPortal to a Different Server, and the Medium Trust documentation.

Hope that helps,

Joe

Re: Problem with webhosting Medium trust

Thank you very much.
Another a little stupid question: On machine, where I am working with VS2010, on your site www.mojoportal.com is every forums post body replaced by message "NeatHtml not found"? On another machine is all ok (the same internet explorer - Google Chrome).

Re: Problem with webhosting Medium trust

I'm not understanding you.

Are you saying you are having a problem with forums on your own site or here on this site?

I don't see any problems in the forums here on this site.

NeatHtml is what we use to prevent XSS (cross site scripting) in untrusted content such as in the forums.
