Text Changes Not Saving

I’m trying to create just a basic (mostly text) page (in visual mode, because I can’t code) and I’m having two issues.

1) After placing an image, the first line of text following the image gets aligned left automatically. If I indent to where I want it, and then click save, it again aligns left when the page reloads. This happens with the first line of text after every image, regardless of how much space I put btwn the image and the text.

2) None of my font sizes are saving to the actual pages. In the editor I make the title huge, and subtitles relatively large (using the Header 1, 2, or 3 selections). But on the actual web site, they show up just a tad bigger than the article text, and there is no difference in size between the title and the subtitles, even though one is “heading 1” and the other is “heading 3” size.

Thanks
