Some of the mystery I figured out. It looks like there are a few things to address here.
Because of my limited time-line I decided to stick to the root dir right now until I have completed development of a multi-domain system, and then migrate the contexts out to their own sub-dirs after I had them working without error from the root dir. It takes a lot of the potential confounds out of tracking down specific issues.
the first issue I’ve come across (for which I’ve submitted a bug report) is that the upload button appears to only upload to the base dir. You can’t nest folders inside of, for example, the images folder and then use the upload button to upload files to them. The files just end up in the base dir. The only way to send files directly to the subdir is to right-click on it and then select upload file.
Meanwhile, putting that aside, I’m not having the problems with paths being messed up in tinymce when I try to link to images/files/etc anymore. I did update to the most recent mce and edited the rb_****** settings to reflect accuracy. So as long as I’m using the single gateway system (not with the plugin but rather with the same functionality in the index.php file as stated above in an earlier post) then the system is working quite well.
Will keep you posted about the subdirs, as I’m getting close to complete.
