Hello,

when trying to upload *.jpg files to my experiment I get the following error message:

"An Security Error, 'securitySandboxError' occurred. May be you trying to upload/download files outside current domain (See "Cross Domain Security" section in manual)" 

The problem may not be Inquisit itself but I can't work out how to fix it or get around it. I am currently still using Inquisit 4 web beta (4.0.0.1). I tried in Chrome and Firefox, my operating system is OS X (10.8.2).

Does any one have an idea what's going on and know a solution?

Thanks :)

Clear your Flash player's local cache as per http://forums.adobe.com/message/4278569. Then retry uploading the files and let us know the result.

Firstly, thanks for your help!

It's weird: I cleared the cache and afterwards it still was not working in Chrome and Firefox. I then tried Safari and it worked.

Good enough for me but I still don't understand what's going on. 

It's some sort of cache corruption issue, I'm not sure about the exact cause.

As for clearing Flash cache in Chrome, see e.g. https://www.youtube.com/watch?v=vwNRXrXO8h4.

I am receiving the same error message as described above.  It persists even after clearing the cache, and clearing the Flash cache.  I have now tried to upload the additional files on three different computers, using IE, Firefox, Chrome, and a brand new install of Safari.  It is not, alas working in any configuration.  Please advise on how I can get my files uploaded - I have now spent over four hours simply trying to get some additional files loaded.  

Thanks in advance,

Kristin

As far as I am aware clearing the Flash cache as outlined here has resolved the issue in the few cases reported so far. I would first suggest you repeat the cache deletion process (and perhaps throw in a system reboot for good measure). If that does not help, let us know and we will take it from there.
