I have an problem, i use the image uplaod file in my form but when i want to delete my picture with the red cross, the explorer for upload a new image is open before i can't delete image. I need to upload a new image for delete the last and i want to have only one image.
The max file inoput in admin is 1.
I have tried to reproduce this issue but failed. You can disable all your plugins except User Frontend and switch to a default theme of WordPress like- Twenty Twelve, Twenty Thirteen, Twenty Fourteen and let me know the results.
