Hello, I just installed the plugin and I’m trying to get it up and running but the test email won’t send and in the STATUS page I get the following error:
FAILED (Undefined index: wp_db_temp_dir)

I searched in the online documentation and this support forum and I cannot find anything about this error so I am not sure how to tackle it.
Also at the bottom of the status page there is another error:
The recommended charset for your database is utf8mb4 to avoid possible saving errors when you use emoji. Read the WordPress Codex conversion instructions (skilled technicia required).
I am wondering why this error is even taking place since I am running WordPress and it has alwyas run with the databse… Even if I knew how to convert it, would it be safe for me to convert the database? Or would WP stop working?
