The old folder permissions confusion again

Hi all,

Ok, been a while since I’ve been on here.

So, I upgraded to 9.8 (inc PHP 7.4 to 8.1). All (mostly) seemed okay and I followed some of the proposed tweaks for older applications in terms of PHP compatibility. Again, all ok.

I also (and this may have been the cause of my issue) tidied up the dev environment’s permissions by changing all folders under /var/www/mydevsite/scriptcase to 755 and files to 644.

Overall, this seemed okay - but on logging on I get this popup: https://share.elixirweb.studio/DOurPgNv

And under “diagnosis” I see this: https://share.elixirweb.studio/d5unJYYO

So I’m guessing some folders (or maybe even files) need something more than 755 (777?). I’ve looked all over for a definitive list of folders and required permissions but I’m not having much luck.

Any ideas, please?

Thanks.
