Warning: count(): Parameter must be an array or an object ... - see soln

Users (Windows, macOS, Linux) with existing PHP7 installation will get above error when running TagUI. This is because PHP 7 has a backward incompatible change for the function count().

This is similar to the issue that happens when macOS users upgraded to Catalina release, because that release upgrades PHP to version 7 - #597

The solution for now is to use the cutting edge version which already has this fixed - https://github.com/kelaberetiv/TagUI#set-up

In a future packaged release, this fix will be part of the zip file and does not require the additional step of updating your existing installation with the cutting edge files.

Thanks @siowyisheng for flagging this!
