The errors are generated from someone else. It looks like Safari 7 from the user agent string of:
Mozilla/5.0 (iPhone; CPU iPhone OS 7_1 like Mac OS X) AppleWebKit/537.51.2 (KHTML, like Gecko) Version/7.0 Mobile/11D167 Safari/9537.53"
I’ll just let it go at this point since it is mobile. I don’t really need it to run those plugins.
