getting errors in wordpress

I installed the plugin and started getting these two errors. Have you seen this problem before, and if so, what do I need to do about it. The link above takes you to the snipboard.io page (since I cannot see how to attach the image here any other way, but hopefully you can see that and make sense of it. I can provide other information if needed, but let me know what that would be.

Thank you for your help,

Jonathan
