I have a very basic strategy I was using in strategy monitor, however after the recent update to WL, I'm not able to get back into strategy monitor. Not sure if it had to do with the new update or something else. I have attached the error. I'm not familiar with coding, so I'm hoping this can be an easy fix. Thanks!

Details of error are attached in pdf.

Please refer to our Knowledge Base (Wiki) > Strategy Monitor doesn't work, notice section with example of the "Root element is missing" error, and follow the procedure to fix it for good.

Also, PDF are suboptimal for posting screenshots and/or error messages. If it's a modal Windows error dialog, you could strike Ctrl-C to copy the underlying error message and Ctrl-V to paste it when replying (a standard Windows shortcut). Please only attach text as text (TXT) and images as images (PNG preferred, MS Paint which is built in any Windows will do it). Simple? You bet!
