7.0.26 working perfect / 7.1.7 – this errors

Wonder can somebody fix it and fork this plugin?

I have no problems with the plugin:

• PHP Version 7.0.25
• System: Linux dd41536 4.4.0-109-generic #132-Ubuntu SMP Tue Jan 9 19:52:39 UTC 2018 x86_64
• Server API: Apache 2.0 Handler
• WordPress: 4.9.2 Network Installation/Multisite with Domainmapping

@csigncsign You are using PHP 7.0 and not PHP 7.1. The problem is with PHP 7.1+

I have no problems with the plugin:

PHP Version 7.0.25

This topic about PHP 7.1

The problem is in mctagmap_functions.php file on line 95:

$scarr = '';

, the variable is used as array later on, but is initialised with empty string, it’s a bad practice, but it worked up to PHP 7.0. To fix this issue, change the line to:

$scarr = [];

Thanks marale

this is hopefully fixed now.
