Don't hang your question on an old topic, but start a new one.

Please note that the commands are case sensitive.

Please note that the commands

and environments

are case sensitive.

And if you post an example please always test it before and post exactly what you've tested. And use the Code button or Select code button from the toolbar to mark your example as code. And please always copy&paste the exact error message from the log-file. And also use code tags for that paste, because line breaks and indents are valid for error messages and only preserved inside code tags.

BTW: 10pt and oneside are defaults of article and can be omitted. Since LaTeX 2018-04-01 UTF-8 is the default and

Code: Select all

\usepackage[utf8]{inputenc}

can be omitted.

Hi Lyke,

welcome to the forum!

It can simply be that you did not choose (pdf)LaTeX but pdf(TeX) as compiler, so \documentclass is undefined.
