Hi Michael, thank you for replying.
1. The article it is in is currently blank with the following code in it
I specified the Default upload folder in Basic Options within the Plugin Manager. (doc_lib)
2. No changes have been made to any of your code.
3. I have tried to upload small png, jpg, and gif files all < 300KB.
4. I have not changed any settings within the Plugins Manager. i.e.
Default Permitted file types (separate by semi-colon. no spaces between).
Permitted MIME types (separate by semi-colon. spaces between allowed).
