DhtmlxSuite 5.1 is not supported with PHP 7. What are the modifications have to do for DhtmlxForm?
What’s not supported on PHP 7? I’m running PHP 7.2 and have several pages using DHX 5.1 - 5.4 with no issues.
dhtmlxForm is a completely JS library and is not related to the php at all.
Could you pleas,e clarify what exactly goes wrong for you.
