My site sculptor site is not displaying correctly in latest Edge Update and other browsers
Hello, My site was built with Site Sculptor a few years ago.
It used to display correctly in Internet Explorer, Microsoft Edge and Chrome.
A few years ago it stopped displaying in Firefox and Safari.
In the latter the drop down menu would display pages shifted to the right.
Large parts of the pages are blank white.
In the old Edge browser, it used to work fine.
In the new Edge browser it is not displaying properly, it is the same now as Firefox and Safari.
In Internet Explorer it works fine.
Can someone help advise what I should do to allow it to work over these problem browsers.
My site is www.ptfefiltervents.com
Site built in Dreamweaver CS6.
Your guidance and help is much appreciated.
With regards
