I've been using JCE for many years and since about a year I've started RSPagebuilder. I really like RSPagebuilder but it lacks the JCE editor for text and the JCE Media browser for image blocks. I usually end up uploading images in one tab in the JCE media browser and then selecting them in the RSpagebuilder in another tab.
Do you know of any way to get JCE working with RSPagebuilder?
I've also asked RSjoomla support:
"JCE hasn't been developed by us and we can't provide insight on its functionality. If this works using a standard Joomla! editor, then you'll need to contact JCE developers directly on this matter to investigate this for you (in the meanwhile you can try checking your JCE options/permissions)."
