I’m getting sick and tired of WordPress because I’ve had problems with hackers and I’m looking at options for another platform. I would be fantastic if you could point me in the direction of a good platform.

    • Hello Borvest,
      Thanks for your comment.
      We are using WordPress CMS for our blog as it is of the safest CMS right now but you can make your blog more secure by replacing your username from admin to custom. You can make your own password rather than using the default one. Use some security plugins and always update them and also WordPress version.
