The line length in the log-files of the LaTeX run are not limited by the editor—in your case TeXmaker—but are a hard coded limitation of the TeX engines. AFAIK it cannot be changed. This is indeed also a problem of several programs (e.g. most LaTeX editors), that try to analyze the log or the ...

\vert is a mathmode command. But instead of using $\vert$, I would suggest to use a \rule[<vertical shift>]{<width>}{<height>}.

The easiest is, to use either LuaLaTeX or XeLaTeX instead of PDFLaTeX. Then you can use fontspec after installing the font on your computer. If the font is installed as system font, you can load it either by font name, e.g.:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{TeX Gyre ...

apacite.bst does not support an entry field isbn (but e.g. a doi ). The supported entry fields can be found in apacite.bst . Just search for keyword ENTRY .

Note also, that apacite is not conform with current APA rules. So it is only one of several author-year styles. If you really need APA, you ...

With BibTeX the sort order depends on \bibliographystyle{…} . So in your case, the publisher should provide this by the bst file it either provides or recommends.

With biblatex and biber , the sort order would be configurable with LaTeX code.

BTW: Please use the code tag instead of the latex tag ...

First of all, please note, I've used the Overleaf link.

I cannot recommend this template. The class has several issues with potentially unwanted spaced . The class uses \usepackage instead of \RequirePackage (which is indeed only a convention inside classes, but the recommendation in the clsguide ...

Unfortunately, all essential information is missing:

• What did you do?
• How did you do it?
• Where do the messages come from?
• What is in the given log file?

Please always try to make a instead of showing only a code snippet.

To place the comma between the line, you could add a \raisebox after the longest line:

\documentclass{article}
\usepackage{amsmath}

\newcommand*\centermathcell[1]{\omit\hfil$\displaystyle#1$\hfil\ignorespaces}

\begin{document ...

You could use hacks like: or draw the square root yourself using TikZ.

Once again: It is not absolutely not clear, what you want. As already told: If you want to show the result of, e.g., \times using \textrm would not make sense, because \textrm does not influence math mode and \times requires math mode. But if you want to show the code, you need \verb , e.g ...
