You may experience issues such as buttons not responding, menus not appearing, or a blank white screen. These are often caused by browser settings or extensions. Follow the steps below to identify and resolve the problem.

Isolating the Problem

To determine whether the issue is a system-wide problem or specific to your environment, check the four points below.
  1. Test in an incognito window Log in using your browser’s incognito (private) mode and try the same operation. If the issue disappears, saved browser data or extensions are likely the cause.
  2. Disable all extensions (add-ons) Ad blockers (such as AdBlock), translation tools, and screen-capture tools can interfere with page behavior. Disable all extensions and check whether the issue persists.
  3. Set the browser zoom level to 100% A zoom level other than 100% (such as 90% or 110%) can sometimes cause click targets to misalign. Verify behavior at 100% zoom.
  4. Test in a different environment (browser, PC, or multiple users) Different browser: If you use Chrome, try Edge or Safari. Different PC: Check whether the same issue occurs on another computer.
