[SOLVED] Users cannot upload profile image

I'm using CB 1.8.1 on Joomla 2.5.6 with no added plugins.

If users try to update their profile picture, when they click "Update" it says, "Your settings have been saved" and they are brought to the member listing but no changes have actually been made.

I can change the images on the backend successfully.

Member list? They should be sent to profile with a success message or back to profile edit with a failed message. Please ensure you've a public and published Joomla menu link to CB profile.

It goes back to the Update Image screen and says, "Please select a file before uploading."

Click "Browse" and select an image then select an image and click "Upload". You don't click "Upload" if you're selecting a gallery image; you simply click "Confirm choice".

After clicking "Browse", selecting and image, clicking "Open", then clicking "Upload", it goes back to the Update Image screen and says, "Please select a file before uploading."

It's like the upload button isn't sending the information when it's clicked.

What type of image are you trying to upload? Believe only PNG, JPG, and GIF are supported.
