I installed CKEditor on one installation of WolfCMS and it worked great.
I installed WolfCMS on another web host, added CKEditor, enabled it, checked the settings, and everything looked OK. In the Pages editor, the CKEditor pane showed up in the Filters dropdown. But when I selected CKEditor for that page, neither a toolbar nor a text window appeared when the page was redrawn. It looks like the kind of problem that can be caused either by some deep and serious incompatibility between/among components, or by a single missing or incorrect character somewhere. I am in clue-reception mode.
One notable difference with the second web host is that I don't have ssh access, and files can only be uploaded by sftp. It is not possible to extract from an archive in the hosted environment, I have to extract on another machine and recursively put the files over. The result was good enough that ckeditor was recognized by the plugins page, but maybe there's something about the way tftp does things that causes this problem. One possibility that comes to mind is the issue of binary vs. ascii mode transfers, but I have FileZilla configured to consider files with certain extensions to be ascii, and the default is binary. Extensions .php, .txt, and .js are to be considered ascii; .png and .gif are not.
I don't know that that issue would necessarily relate in any way to the behavior I'm seeing, because while I can imagine improper copying of images messing up the toolbar, I wouldn't think that could prevent the textarea from being drawn.
Would ckeditor, or wolfcms, create log files that would possibly be worth looking at? Is there a way to enable additional logging by editing a file somewhere?
I've already uninstalled ckeditor, deleted the ckeditor tree, re-put a fresh ckeditor tree (freshly extracted from the zip file), and re-enabled the plugin, and I get the same result.
So, clues?
