Hi Bruno,
It’s now on GitHub (first time I use it by the way). You can find here: GitHub - relaciones-internacionales-journal/ojs-2-4-2: Previous OJS customization for the academic online spanish journal "Relaciones Internacionales"
I’ve updated my first post to include this link.
As you will see, most changes are just re-ordering blocks of code or added HTML in “templates folder” files, so I don’t know if I any plugin can do that. But adding Bootstrap or Font Awesome CSS & JS could be easily moved into a plugin (I think). Anyway help would be greatly welcomed.
I’m now testing the upgrade to 2.4.6 (test repo is also on Github) and I’ll also try to clean modifications. Hope that it’ll ready in a few weeks.
Thank you again, cheers,
Andy
