Brand new install, v156, php 7.2, installed with zc_install, only plugin installed TY tracker,
I am trying to perform a SQL patch for the dropship and pdf PO l\plugin but don't know how to use it under tools/install sql patches. I have copied and dropped the sql file provided into the window but get the following:

"WARNING: An Error occurred, please refresh the page and try again.If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields."

I'm sure this is because I don't understand what I am doing and have not entered something correctly. Can someone help?
