Page Layout ⇒ Unexpected blank page and text running out of the page

[arthurfrancisco]

Hi!
I'm a beginner in LaTex, and I've been facing 2 problems while starting to edit this article in Overleaf.

1. There is a unexpected, sudden, blank page and I couldn't manage to find its cause;
2. In the next page, text is running out of the page.

Do you know how to fix this?
Thank you.

Welcome to the forum.

For a beginner, you got quite the preamble. You copied that from somewhere to save some time. That is a bad idea. It contains stuff you shouldn't do.

You only have sectioning commands in your document. Add some content, i.e. some text and your problem will disappear.

[Ijon Tichy]

Some additional notes to the shown example:

• Package subfigure is deprecated. You should replace it by one of the alternatives mentioned in the linked package information.
• Font size commands like \Huge do not have an argument. They are working as a switch, that is valid until the end of the current group. Moreover, you should also always take care, that they are valid until the end of the current paragraph, because TeX always uses the line spacing, that is valid at the end of the paragraph for the whole paragraph.
• Encapsulating of \maketitle into a titlepage environment is nonsense. Use either a free defines title page inside a titlepage environment or \title etc. and \maketitle.
• Usage of \bibliographystyle and \bibliography is not wrong. But style plain supports only English. The more modern solution with biblatex and biber would be multilingual and therefore recommended.
