Problem with HTTP headers (Canada)

Hi Locopon,

Whenever I access the editor, I get the following two errors (even though the editor comes up and appears to be working OK) :

AssemblyVersion: 03.01.01

This is followed by :

Any ideas?

Re: Problem with HTTP headers (Canada)

FYI - I worked around the error by changing this line in web.config :

StylesGeneratorPath="~/Providers/HtmlEditorProviders/DSFCKEditorProvider/DSFCKStyles.aspx"

To :

StylesGeneratorPath="~/Providers/HtmlEditorProviders/DSFCKEditorProvider/FCK2/fckstyles.xml"

Of course, this causes the editor to use the default styles inside the editor area, but that's fine for me.

Re: Problem with HTTP headers (United States)

As you will notice the bottom of the error is the blower HTTP compressor.

Please see this post, as I have a better solution for you:
http://dnn.tiendaboliviana.com/web/Forums/tabid/72/forumid/7/threadid/416/threadpage/2/scope/posts/Default.aspx

Locopon -- can you include that post in your docs so people with blowery HTTP compression can get styles to work?

Thanks, Will G.

Thanks, I'll check it out.

I'll probably just stick with referencing the .xml file though. Since I don't really need the editor styles to match that of the site I figure I may as well elliminate the overhead of running DSFCKstyles.aspx altogether by referencing an .xml file that is essentially empty. My FCK editor now loads in a snap!

Re: Problem with HTTP headers (Bolivia)

Yes, thats the idea. Use styles as you need. Many people need DNN styles and many don't.

I am using blowery compression and all works ok, but I will review that part to see what is happening there.

A workaround for this could be adding

~/Providers/HtmlEditorProviders/DSFCKEditorProvider/DSFCKStyles.aspx

to the http compression module configuration section (You can set what pages to exclude)

Next release will include an option to set this feature by module.
