Empty Bibliography error despite implementing multiple fixes?

Question

I have been trying to sort this out for almost a straight day and any fix I find for similar problems doesn't seem to work. I am using TeXStudio to write my thesis and my bibliography isn't being included at the end of my file, nor is the file referencing properly.

My main file preamble is as:

\documentclass[
11pt, 
english, 
singlespacing, 
nolistspacing, 
headsepline, 
]{MastersDoctoralThesis} 

\usepackage[utf8]{inputenc} % Required for inputting international characters
\usepackage[T1]{fontenc} % Output font encoding for international characters
\usepackage{indentfirst}
\usepackage{graphicx}
\graphicspath{ {Figures/} }
\usepackage{subcaption}
\usepackage{enumitem}
\usepackage{url}

\usepackage{palatino} % Use the Palatino font by default

\usepackage[backend=biber,style=authoryear,natbib=true]{biblatex} % Use the bibtex backend with the authoryear citation style (which resembles APA)

\addbibresource{Bibl.bib}

and my bibliography is as follows:

@misc{Missi34:online,
author = {},
title = {Mission | UoS3},
howpublished = {\url{http://generic.wordpress.soton.ac.uk/uos3/mission/}},
month = {},
year = {},
note = {(Accessed on 04/11/2016)}
}

@article {GRL:GRL13482,
author = {Anderson, Brian J. and Takahashi, Kazue and Toth, Bruce A.},
title = {Sensing global Birkeland currents with iridium® engineering magnetometer data},
journal = {Geophysical Research Letters},
volume = {27},
number = {24},
issn = {1944-8007},
url = {http://dx.doi.org/10.1029/2000GL000094},
doi = {10.1029/2000GL000094},
pages = {4045--4048},
keywords = {Magnetospheric Physics: Instruments and techniques},
year = {2000},
}

@misc{DICE83:online,
author = {},
title = {DICE - eoPortal Directory - Satellite Missions},
howpublished = {\url{https://directory.eoportal.org/web/eoportal/satellite-missions/d/dice#foot17%29}},
month = {},
year = {},
note = {(Accessed on 04/12/2016)}
}

@manual{CoilManual,
title = {Gyroskop U 52006},
date = {2015},
OPTlanguage = {English},
OPTorganization = {3B Scientific},
OPTpagetotal = {3},
OPTurl = {\url{https://www.3bscientific.co.uk/product-manual/1000906_EN.pdf}},
OPTurldate = {(Accessed on 04/13/2016)},
}

It claims that the bibliography is empty at the \printbibliography line even though I have been citing them in my main text. When I go the cite something the list of references appears but puts just the label in the text instead of number or information. For example,

The product manual (CoilManual) gives an equation to calculate the ﬁeld generated inside the coils.

I have tried using \cite, \cite* and \autocite and nothing helps.

I have done the pdflatex-biber-pdflatex sequence many times, have ensured that my default bibliograghy is biber and not bibtex. It may just be something small but I can't find a solution anywhere.

if there is, what is the exact error/warning message you get? — naphaneal, Apr 13 '16 at 14:35
Note that your .bib file is not optimised for biblatex, you can use the url and urldate field instead of note and howpublished. The code so far looks OK, though I don't know if MastersDoctoralThesis can cause some trouble here. We would need to see the errors and warnings from the .log and.blg files. Check also if your editor is really set up correctly. — moewe, Apr 13 '16 at 14:46

The errors and problems you get are comming from one bad bib entry.

Please see this changes for the bib entry DICE83:online:

@online{DICE83:online,
  author = {},
  title  = {DICE - eoPortal Directory - Satellite Missions},
  url    = {https://directory.eoportal.org/web/eoportal/satellite-missions/d/dice#foot17%29},
  urldate = {2016-12-04},
}

The problem in the old version is the %, causing that the field howpublished is never ended ...

With the changes above I can compile without error messages the following complete MWE (package filecontents only used to have bib file and TeX code concatenated to one MWE):

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@misc{Missi34:online,
author = {},
title = {Mission | UoS3},
howpublished = {\url{http://generic.wordpress.soton.ac.uk/uos3/mission/}},
month = {},
year = {},
note = {(Accessed on 04/11/2016)}
}

@article {GRL:GRL13482,
author = {Anderson, Brian J. and Takahashi, Kazue and Toth, Bruce A.},
title = {Sensing global Birkeland currents with iridium® engineering magnetometer data},
journal = {Geophysical Research Letters},

number = {24},
issn = {1944-8007},
url = {http://dx.doi.org/10.1029/2000GL000094},
doi = {10.1029/2000GL000094},
pages = {4045--4048},
keywords = {Magnetospheric Physics: Instruments and techniques},
year = {2000},
}

@online{DICE83:online,
  author = {},
  title  = {DICE - eoPortal Directory - Satellite Missions},
  url    = {https://directory.eoportal.org/web/eoportal/satellite-missions/d/dice#foot17%29},
  urldate = {2016-12-04},
}

@manual{CoilManual,
title = {Gyroskop U 52006},
date = {2015},
OPTlanguage = {English},
OPTorganization = {3B Scientific},
OPTpagetotal = {3},
OPTurl = {\url{https://www.3bscientific.co.uk/product-manual/1000906_EN.pdf}},
OPTurldate = {(Accessed on 04/13/2016)},
}
\end{filecontents*}

]{biblatex}
\addbibresource{\jobname.bib}


\begin{document}
Some Text.\nocite{*}

\printbibliography%[]
\end{document}

and the result:

Conclusion:

If you use biblatex then please rework your BiB file because biblatex uses other field names (url instead of howpublished, etc.). If you want to use the advantages of biblatex please use the field names, biblatex is made for.
