[coiby]

Describe the bug

There are three unusually large tables,

Table	Rows	Size
wpnf_wpmailsmtp_debug_events	18,669	121.6 MiB
wpnf_options	7,750	120.0 MiB
wpnf_actionscheduler_logs	~964,691	115.8 MiB

To Reproduce
Steps to reproduce the behavior:

1. Visit the database via hostinger
2. Click "Size" to sort the tables by size

Additional context

There are two problems with these large tables,

1. It will have an negative impact on the site performance
2. It make its a bit slow to download/clone database for purposes like developing or debugging.

For wpnf_wpmailsmtp_debug_events, it's huge because debugging has been enabled.

1. We can follow https://wpmailsmtp.com/docs/how-to-debug-email-sending-issues-in-wp-mail-smtp/ to disable debugging.
2. We can delete the debugging events via WP Admin Panel -> WP Mail SMTP » Tools » Debug Events

I've emptied wpnf_actionscheduler_logs by running SQL query truncate wpnf_actionscheduler_logs.
