Problem: The client experiences a white screen when clicking on a translation in the advanced translation editor, accompanied by a JavaScript error in the Chrome developer console indicating a 'SecurityError' related to 'cssRules' in 'CSSStyleSheet'.
Solution: Client identified that the issue was caused by a conflict with the NordVPN browser extension. We recommend disabling the NordVPN extension when using the advanced translation editor to avoid this issue. If you wish to continue using the NordVPN extension, we suggest contacting NordVPN support for further assistance.
