The server behaviors were removed for a very good reason. The code that they generate won't work in PHP 7, which is scheduled to be released next week. Nor will it work in a lot of sites that run PHP 5.5 or 5.6 because some hosting companies have disabled the original mysql functions in PHP.
You can make a strong argument for Adobe to update the server behaviors to work with MySQLi or PDO (many people have already done so), but you're living on borrowed time if you continue to rely on the old server behaviors. Even if Adobe created updated versions of the server behaviors tomorrow, you would still need to recode all your pages because the code in the server behaviors cannot be easily replaced.
As a short term solution, drop back to CS6 which has native support for the Server Behavior Panels.
- Log in to Creative Cloud Desktop App.
- Click on Apps > ALL APPS.
- Scroll all the way down, click on PREVIOUS VERSIONS.
Long term solution, replace old Server Behaviors with a modern commercial extension:
- MySQLi - http://www.webassist.com/dreamweaver-extensions/mysqli
- PDO - http://www.dmxzone.com/go/22096/updated-replacing-dreamweaver-server-behaviors-with-dmxzon e-extensions/
Thanks, Dave & Nancy! I'll check out both WebAssist and PDO. Going back to CSS 6 is just delaying the inevitable.
As an afterthought I'm wondering why the server behaviors for my current pages still work? They are on the same site. The old pages are the desktop/laptop version of my site. Whereas, the new pages that don't work are for tablets/smartphones. They are all with the same hosting provider and the same URL!
My guess with nothing more to go on is that your Tablet/Mobile site has code errors that need to be reconciled.
HTML - http://validator.w3.org/
HTML5 - https://validator.w3.org/nu/
It might be something as simple as unbalanced HTML tags or poorly defined SQL queries.
Compare codes from both sites to see where the code discrepancies occur.
