I do get this error all the time as part of the Error:
This is BibTeX, Version 0.99d (MiKTeX 22.1) The top-level auxiliary file: thesis.aux The style file: plain.bst I found no \citation commands---while reading file thesis.aux I found no \bibdata command---while reading file thesis.aux (There were 2 error messages)
Process exited with error(s)
I have looked through many entries on here already, but none of the suggested solutions worked. Here is my code [I excluded \title \fancyheader and other small changes from the post below]
\documentclass{article}
\usepackage[affil-it]{authblk}
\usepackage{selinput}
\usepackage{amssymb,amsmath,mathtools,gensymb,upgreek}

I am using TeXmaker and checked that the settings are on biber. I am creating the .bib file via JabRef and it is properly filled. However, the .bbl file remains empty. I have plenty of citations in the \include{theory} section and used \nocite{*} just to be sure I am definitely citing something. That shouldn't cause any of these issues, should it? I also noticed that in the .bib file some %-signs are part of abstracts and in the urls – would that be problematic?
backend=biber. So you should use biber and not bibtex. See e.g. https://tex.stackexchange.com/questions/230942/i-found-no-citation-commands-while-reading-myfile-aux?rq=1 – Ulrike Fischer Apr 05 '22 at 13:08biber(necessary forbiblatex) in your editor? TeXmaker: https://tex.stackexchange.com/questions/44040/biblatex-biber-texmaker-miktex – FHZ Apr 05 '22 at 13:20\usepackage. Biber is a helper program (just like BibTeX) that you need to run on your document. https://tex.stackexchange.com/q/63852/35864 explains brilliantly what Biber and BibTeX do. https://tex.stackexchange.com/q/154751/35864 explains how you can set up your editor to run Biber for you. – moewe Apr 05 '22 at 15:04
