I had a strange issue when trying both upload managers just now while posting pics in the following link
https://forum.oneclickchicks.com/show...&postcount=662
1: When the pics were downloaded they were all in uppercase. The advanced file manager was not able to recognise .JPG extensions. With the browse button open if I renamed the file to .jpg I could see the browsed folder populating with the file the second I renamed it.
2: With the extension now renamed to .jpg I uploaded but got an error message. This seems to be a result of the original file names not being in English. I renamed the files to 1, 2, 3, etc and they uploaded without issue.
For reference one of the original file names was: ИГОРЬ+ГРЕЙС+2012+БАЛАКЛАВА+ТАРХАНКУТ+(82) (copy).JPG
The files opened without issue on my system. For reference, I am using Linux but I do not think that was the issue as I have always been using it since I joined the site and have not had any issues before now.
It is worth noting that of the 5 or so files I uploaded, only two were recognised using the basic manager. All were recognised after a full renaming. The basic manager did not distinguish between .JPG and .jpg
