There are quite a lot of articles in this regard. I will not talk much about the problems I have encountered.
I also made the configuration by referring to the net text. CKEditor went smoothly and encountered no problems. In the net text, we must add "class =" ckeditor ". I didn't add any problems.
However, CKFinder configuration does not always work, and it is depressing for a long time. Finally, we found that CKFinder. SetupCKEditor (null, 'ckfinder/') in the net text. The problem should be that setupCKEditor, s is in lower case ~~~ In addition, it is said that do not add/before ckeditor. In my own environment, you must add/to work normally. Somehow.
At last, I hope that you will be careful when posting articles, and pay special attention to the case-sensitivity issues. Otherwise, readers who may refer to your articles will suffer.
