Tom, you are DA MAN! Thank you!
I am not using and am kind of hesitant to use any caching plugins. So will leave things as they are. I minified some js file from the theme successfully and this raised my google-speed a bit. Some css couldn’t be minified in this way because of some errors, but that’s all right for now. I’ll leave. 😉
The code for table borders worked! Thank you! Keep up your amazing work!
