ERROR - Cannot find control file 'thesis.bcf'! - Did latex run successfully on your .tex file before you ran biber?

Hi all,

Krishna - thank you for the outstanding template! New player to LaTeX here, popping a simple error with the template.

Just using default settings

\documentclass[a4paper,12pt,times,numbered,print,index]{Classes/PhDThesisPSnPDF} No settings changed in Class file

On compiling, generates the error: ERROR - Cannot find control file 'thesis.bcf'! - Did latex run successfully on your .tex file before you ran biber?

I have checked:

• Run Latex alone (Build & View): exits normally, no errors
• When then running Bibliography alone, error pops:

  
  INFO - This is Biber 2.12
  INFO - Logfile is 'thesis.blg'
  ERROR - Cannot find control file 'thesis.bcf'! - Did latex run successfully on your .tex file before you ran biber?
  INFO - ERRORS: 1

Process exited with error(s)

Similar to [Issue 204](https://github.com/kks32/phd-thesis-template/issues/204) but I am not trying to change any reference settings, happy to use `natbib` as default.

Seems to be somehow calling Biber? I've checked through thesis.tex, preamble.tex and cannot see that I have changed comment/uncomment on any lines. Any ideas?

I note TexStudio > Preferences lists Biber as default bibliography tool? Could that be the cause?

Using TexStudio 3.0.1 on Mac OS Mojave

Problem solved - rookie mistake, but maybe will help somebody coming after me.

TexStudio had defaulted to biber as bibliography tool (TexStudio > Preferences > Build > Default bibliography tool) - changed back to BibTex, but need to restart TexStudio for changes to take effect. Sigh.
