Help to tweak the VPS server to ensure all websites running without going down every now and then.
Hi, we are an e-commerce company selling products online. Our shopping carts are based on Opencart. The websites are hosed on a VPS server. However, the websites go down or become very slow almost every other day. We've been applying different kinds of security measures to the server but not helping. We are looking for a skilled hosting/security expert to help us. Thank you.
