Email Issue with Chrome Extension Grammarly
On the Email screen, if you receive a popup error that reads, "Error while executing filter StripScriptsFilter - TypeError: Cannot read property 'replace' of undefined," please review your Chrome extensions to make sure that Grammarly is disabled.

Grammarly extension has a script/code that accesses text fields on a given webpage. It also attempts to modify the page to provide feedback to a user. This code, which is owned and maintained by Grammarly inserts its own HTML and also sometimes works incorrectly causing pages to crash. PCR Educator has no technical capability to access Grammarly code and to fix it and thus the only solution is to disable Grammarly extension or use "incognito" browser feature.

This is a known problem that affects many web applications:
