Why am I getting XML errors when printing shipping labels?

[StillAlarmLthr]

I am getting the below error when printing shipping labels.  This occurs if I print the label and packing slip together or if I print just the shipping label by clicking that.  The only way I can print the label is to exit the order, go back into the order, and press, "Reprint label."

This happens regardless of browser, but just for good measure I signed out of all accounts, deleted all cookies, and deleted all cache. 

I made no changes between when it worked and when it stopped working.  This never happens when printing just the packing slip, regardless of how I chose to print that.

Did you get this fixed?  So far tech support has been awful. 
"I'm having this error.   I logged out, cleared cookies/cache,....."
"Did you try logging out?"  "Did you try clearing cookies and cache?"

I had this problem and fixed it by logging out of Shopify completely and logging back in. You might try using a different browser or incognito/private mode on your browser if that doesn't work.
