Not sure if I'm the only person getting this, but I tried to make a post which contained LaTeX codes and I could not preview the result. Where the LaTeX output should have been there was linkable blue text that said "LaTeX graphic is being generated. Reload this page in a moment." If I opt to reload the page the same thing happens. Prior to the recent changes, I never had a problem previewing a post which included LaTeX codes. Although I think my recent attempt was the first time that I tried to start a new thread so perhaps it had something to do with that. Should I be doing something different?
