We will need to diagnose by checking your admin, so please if you can provide link and login ... It's always been like this, or did it recently happen?
Just wanted to say that usualy it's some server issue, Suhosin, Mod_Security or as it was in this case - Safe Mode. If there is nothing suspicious - the uploader works.
Hello, I have same problem about uploading images in admin interface. I installed Imagevuex 2.7.5.2 to my webhosting. Uploading images to FTP is no problem. In Admin Interface uploading does not work.
Will need a link and login to your admin to diagnose. .What size images are you uploading? You can't upload large size images without using the resize feature ... Your server most likely does not support this.
