This website is running GravCMS I am using this becuase it is one of the few that don't require a database to function it's all done using txt files. This prevents a few sql related issues.
I have used my fair share of CMS and other than Jaws I enjoyed using Grav and I have been using it for years now.
I strongly encourage the use of txt based CMS's as this prevents a lot of SQL errors such as cross site, injection etc.. however this is still prone to php errors but these aren't as bad as sql errors.
