cffileupload displays an X

[MusicManMD]

I have a client where 3 computers are not having this issue, however 1 computer is and the IT staff is saying that it's my code (Okay).  When this users goes to a page where there is cffileupload code, all they see is a large 'X'.  Does anyone have an idea where I can go to start troubleshooting this issue for this one computer?  There are no error within the browser logs or any js errors.

Thanks in advance for any help!

I hate to say it, but.. "not enough information.. insufficient data.."

Since it is affecting only one computer, it's a 99% likely thing that your code is guilt-free.  Most likely cause is that the one computer has a setting (network security, browser security, something) that isn't in line with the other three.  OR, could it be that computers 1 through 3 are using browser "A" and the fourth is using browser "B"?  It could be a DNS issue with that one computer.  It could be many things.  Are you using JavaScript or jQuery or MooTools??

I would analyze the network connections of all four, noting any differences between the first three and the fourth.  Then check browser settings (assuming all four are using the same browser.)

HTH,

^_^

PS.  Is the fourth computer a Mac or *nix OS??

Nope, they are all the same OS and browser.

That is probably because that particular computer used a browser on which Flash was either disabled or not installed. ColdFusion's multi-upload widget requires Flash to display. So, make sure that Flash is installed and enabled on the browser.

BK, good catch!  I'll check this on Monday, thanks!

@MusicmanMD, any joy getting rid of the X?

[MusicManMD]

@BKBK, you were right on.  They all had Adobe Flash on their machine however the one with the 'X' was missing a second Flash plugin.  Once installed everything worked as it should, with no apologies from the IT staff. 

Thank you!
