BcmsFckeditor fails with browsercms 3.5.3

Hello Guys, I was trying to upgrade the existing browser_cms project to latest version. Had use the bcms_fckeditor as well. But when trying to load page where fckeditor available than it shows some js and xml loading error.

Here i have pasted the error.

JS error. "NetworkError: 404 Not Found - http://localhost:3000/assets/bcms/site/customconfig.js" NetworkError: 404 Not Found - http://localhost:3000/bcms_config/fckstyles.xml" - fckedi...ecko.js (line 68) D is null [Break On This Error]     ...,H,A);};var I=FCKDomTools.GetNextSourceNode(C,true,1);while (I){if (I==D) break;... fckedi...ecko.js (line 53)

XML loading error. Error loading "/bcms_config/fckstyles.xml" (HTTP Status: 404). Do you want to see the server response dump?

bcms_config/fckstyles.xml => Already available under public directory of my rails app.

Using browsercms (3.5.3) bcms_fckeditor (1.2.0)

Can anyone guide me to resolve this problem?

Hello Guys,       Found the solution!!! By placing ckeditor & fckeditor assets under assets directory of app. But still image from Amazon s3 fails to load.
