Turns out it IS about the host. It started to happen to the other admin @ Spain too. I have been emailing them saying their server was banning my IP, and they kept saying according to their records, no IP was banned. Yesterday they emailed me saying “we have found out that our server is banning your IP”. And then they went into the wp admin panel and disactivated all my plugins – without even consulting me. I told them to fix this asap, and since 28 hours, I didnt hear a single reply from them and I sent 6 emails. I heard they were good but this was THE WORST VPS host I’ve ever seen. Long story short: myhosting.com sucks big time – do not ever go near them.
