I teach people on a daily basis how to use WordPress, from the ground up. A few face-smackingly simple issues come up time and again.

1) Pasting from Word will make your posts look funky

Anytime you copy and paste directly into the WordPress editor, from Microsoft Word, another website, or any other outside source, you run the risk of it looking, well,  a bit funky ,when you publish it. This is because other applications, especially Word, have their own set of formatting that gets carried over when you copy/paste. Usually this ends up conflicting with the formatting and styling of your theme. You may not realize there is an issue until you publish the post and something looks off – the fonts don’t quite match, or the spacing is strange. 9 times out of 10 in these cases, it’s because you copied/pasted from Word. To avoid such issues, simply use the 2 clipboard buttons on the second line of the post editing toolbar with the T and the W on them.
