Just downloading a website that was set up with an old cms that is oudated now
as it needs PHP 7.4 support. The owner was sad to loose the content as he puts
a lot of love into it. Migrating was a too much work as the website has a huge
amount of pages. 
Httrack made my day as I can offer a static version of the contents now to
archieve the contents. Even all gallery functionalities work after small
changes (due to the altering of pathes).
Just want to leave that feedback. The tool is amazing folks. Thanks a lot!
