This is now solved using the link above.
It is worth noting that copying and pasting the code from the above link doesn't work straight away as, for me at least, some of the comments and code lines merged. The only changes are to the function get_file_arguements from line 1120 approx.
This is the code I used, from
https://diocesanos-es.translate.goog/blogs/equipotic/2021/01/02/actualizado-moodle-a-v3-10-en-servidor-de-1and1-ionos/?_x_tr_sl=es&_x_tr_tl=en&_x_tr_hl=en-GB&_x_tr_pto=wapp
I hope it helps.
