Hi,
I have been searching in the forum and it seems that some other users/developers are having the same issues with FC 3.0.4 on Joomla 3.4.3. I saw a topic showing this same issue
there
As it was clearly explained for the upload process:
1. so you clicked "Add files" button and the popup opened to select local files
2. after selecting them , you need to click ok so that they are added to the list
3. then you click "Start upload" button
4. the view is refreshed
5. you click the TAB "Files list" to show the files
6. you select the file that you want to add to image field of item form
The issue happens at step 5, it seems that all images are uploaded correctly, however, when we click on the 'Files List' tab, there are no images at all! I don't know is this is a known issue or if there had been a fix for this issue but it is very annoying to upload each image one by one when we have more than 20 images for each item!
If a fix was found for this or is on its way, please let me know urgently, my site is under development, so I can provide admin details for reproducing the error, so, please get back to me about this issue.
