Previewing posts display correctly, then once published...

the html breaks. I can preview an already published post and it will display fine, but actually viewing the blog breaks the html.

I had a link and it just appears as plain text, and the gallery I had attached to the post becomes this text:

#gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 100%; }
#gallery-1 img {
border: 2px solid #cfcfcf;
}
#gallery-1 .gallery-caption {
margin-left: 0;
}



EDIT: Solved this by changing Configure EXCERPTS > Posts or EXCERPTS on Home Page? > Full Posts
