I recently uploaded a site which include the tinymcpuk that contains tiny_mce. During the off line testing, everything including image and plain test pasting are all working perfectly. But while online, the image uploading and test pasting stopped working. Pls, can anyone be of help

No link nothing? Well, i am a professional in using Tinymce and many others too. This happens because of the way the javascript works.

During configuration of the File Managers (depending on what you are using pwd file browser or the native one of Tinymce - cant remember the name now).

You configuration for the file manager is usually relative or absolute, whichever one you are using, you will also need to configure the file manager too,
based on server settings.

If you are not too good in figuring out how to do the relative configuration, and use absolute config. Then you have to reconfigure it again online.
