Backwards compatible?

[Cavediver]

I wrote my website (www.cavediveflorida.com) in 2005 using Dreamweaver 4.0 and have maintained it with that version using a machine with Windows 7. It was not running very well, which is no surprise. Now I have a Windows 10 machine and I am looking to use the latest version of Dreamweaver.

Looking for opinions about whether or not this new Dreamweaver can seamlessly integrate with the code from Dreamweaver 4.0. and allow me to continue maintaining/editing my website?

Any help appreciated.

I've had a quick look at a couple of pages from your website and there is nothing in them that is Dreamweaver specific. Its just standard html code albeit old code, a lot of it is deprecated now but that wont stop any version of Dreamweaver showing it. You might get some code warnings about certain tags being outdated but thats about it.

I'll mention this but its been known for donkies years the way you have your products linked to paypal is insecure. Anyone can change any of the prices BUT if you have someone on the other end manually checking the price sent is the correct price associated with the product its not an issue. Its just if you have someone at the other end totally oblivious.

It looks like you have manually set up the Paypal buttons - in that case you should ALWAYS deploy the encrypted button, which would be available from your Paypal user interface. Those using a database should check the price being sent to Paypal is the same as that in the database. It was not such a big issue back in the day but things have moved on since those times - a lot more are technically aware of how to manipulate the source code of a page.

Thanks for the PayPal comments---So my next question is can I use just any HTML editor such as WordPress to continue editing my site?

Wordpress is run by php so unless you port all of your current code over and make it compatible with the way Wordpress php templates works then, no you cant use Wordpress but you can use any normal HTML editor like Atom, Sublime Text, VS Code, Brackets, Komodo Edit - they are all freely available to use.

HTML code is HTML code.  Any good code editor will work.  But unfortunately, old websites are not like fine wines and collectibles. They don't get better with age.  After 15 years, you really need a new site that performs well on ALL devices.

Whichever tools you decide to use (and Dreamweaver is a good site management tool), your success or failure rests solely on your skills as a web developer.  Failing that, you should hire an experienced professional to help you or switch to a DIY online site building platform like Wix or WordPress.  

Finally, the non-secure HTTP server is a concern.  See browser screenshots below.  You can get free SSL/TLS certificates from Let's Encrypt or Cloud Flare.  Or ask your hosting provider to help you.

Good luck!
