Bitnami Errors on Wordpress Lightsail (AWS)

Question

I have installed a fresh copy of Lightsail on AWS and just All-In-One Migrated my theme to the new hosting platform. (I'm quite new to both Lightsail and Bitnami).

When I check the Bitnami Diagnostic|Testing Tool , I get these warnings, relating to the All In One Plugin .

How important are these? And if need too, how do I clear them?

The site is working well, I don't seem to have any permissions issues when moving files, caching the site or installing plugins, and the Wordpress site health is 100% good.

Any explanation on what to do would be great, thank you.

Since they're warnings, and everything seems to be working fine, you're probably alright.

What it's probably telling you is there's some sort of problem with writing to the temporary directory WP wants to use, and it had to fall back to the system directory instead. You can look in php.ini at the upload_tmp_dir and make sure the account you're running these installs with has write access there (and that it exists in the first place).
