This works great! However, I've run into a problem. Uploading large files (e.g., PDFs), I get the following error:
"Unknown error in act_upload"
If I try a smaller, 3 or 4 MB, file, I get a different error:
"The uploaded file exceeds 2M bytes."
I can't seem to find where the max upload size is set in CKEditor or KCFinder.
