Hello all,
I am having the same problem that was posted here (http://support.swiftideas.net/forums/topic/unable-to-select-media/). When I try uploading an image of any size, I receive the error: An error occurred in the upload. Please try again later
In addition, even though I receive that error, if I go back into the media library a few moments later, the images have successfully been uploaded, even though when I tried completing the upload minutes before, it only generated the error message for me.
I have disabled the revolution slider to see if that was it, but no dice. I still received the error when trying to upload a file.
FWIW, I am running a WPMU, but I don’t think that has anything to do with it.
From what I have noticed, the error seems to be occurring as the files are ‘crunched’ and the error message then comes through.
