White screen (or crash) occurs when logging in

If your students experience a white screen or crash when logging to your LMS via LockDown Browser, it is possible your LMS homepage contains large image files.

LockDown Browser does not cache images (like a standard browser does) and overly large images on your homepage can result in problems with LockDown Browser loading the page. These large files also increase server load and bandwidth, potentially resulting in sluggish server behavior even when using standard browsers.

We recommend that you investigate each image on the page that first loads upon a login. A best practice is to reduce all images to 40-100kb in size.
