My website frequently faced 503 and i found out it is due to the RAM is consumed almost down to empty in server.
After sometime of checking, it seems to be the error coming from the Cloudflare plugin. But even horrible is when i disable the plugin, the whole website is not loading
i can enable the plugin from wordpress.com and everything back normal, but still low ram when I editing and publishing new products as well.
I have no idea why disabling the plugin could cause the whole website down, need some expert to advice this.
