The file exist problem seems be right through Moodle 2.0.2, whether inserting an image within a quiz question or within a Moodle page. Here is what's happening, I will use the quiz question as an example:
- Insert an image within a quiz question then save the question
- Edit the question and remove the inserted image and save the question again
- Again, edit the question and try and insert the same image within the question but recieve an error sayin the 'File exists'.
I know about MDL-26388, is there any progress with the File exists error?
