Suddenly, I couldn’t login into my JIMDO account, which is the hosting service I’m using. So I couldn’t post anything. I sent an enquiry to support desk many times, but they didn’t reply to them. After more than a week, I got their reply. They apologized but they never mentioned why my account was suspended.
BTW, I finally got my web hosting service back. After getting my account back, I immediately saved all my data on the JIMDO service by using the software produced by HTTrack Website Copier. This was a very useful tool to save data quickly. That was easier than I thought.
