Glossary Links offset

When using the glossary as documented, the page numbers in the glossary are correct, but the link on the page numbers are offset by the number of pages within the front matter.

This issue is caused by a configuration in hyperref and can be resolved easily, please check: https://tex.stackexchange.com/a/21722

I have verified that these changes produce correct results.

When you say "the link on the page numbers" do you mean where the glossary item links to is offset?

Could you provide a minimum example for me to recreate (i.e. strip out all your content and just put some lipsum text in)

I think that maybe only the [plainpages=false] option is needed (https://anorien.csc.warwick.ac.uk/mirrors/CTAN/macros/latex/contrib/hyperref/doc/hyperref-doc.html#x1-10500011.2)

Sure no problem. WME:

%% ----------------------------------------------------------------
%% Thesis.tex
%% ---------------------------------------------------------------- 
\documentclass[sotoncolour]{uosthesis}      % Use the Thesis Style with custom link colour
\hypersetup{colorlinks=true}   % Set to false for black/white printing

\usepackage{glossaries}
%% ----------------------------------------------------------------

\makeglossaries
\newglossaryentry{test}
{
    name=test,
    description={Click the page number}
}


\begin{document}
%% ------------------ FRONT MATTER ORGANISATION -------------------
\frontmatter

So when you click the page 1 in the glossary, it jumps to page i instead of 1. To answer the question: Yes I mean the glossary item it links to is offset

I couldn't get it to build, says "could not find Thesis.gls" is there an additional step I need to run to compile it?

Overcame that issue, I had to run makeglossaries

However, then I got the following error:

(./Thesis.gls
! Missing $ inserted.
<inserted text>
                $
l.5 ...etentrycounter[]{page}\glsnumberformat{1}}}
                                                  %

Any idea what might cause that?

For some reason, latex doesn't like the arrow in the glossary (it's working fine on overleaf so I didn't realise).

I've updated the MWE above.

Run latex -> makeglossaries -> pdflatex and it should compile.

Thank you for the recommendation. I've tested it and integrated the change and it doesn't seem to have any negative effects on other links in the document (contents, references etc.). Phew!

Thank you!
