It is heavy loaded, some requests work some don't. A site on a single server like here is not made for thousands of bot requests per second
Maybe I should at some point consider using Cloudflare services.

Enabling the bot filter may help a little, but since some of these new bots are not filtered by it, it won't solve all issues.

I've enabled the bot block a couple times already today

500 Internal Server Error on the main site . Happened twice today ( don't remember the time for the 1st one , 8:54 PM ( Baube's time ) for the second one
