 * Hi there,
 * I’ve found this warning checking php compatibility
 * `FILE: /plugins/duracelltomi-google-tag-manager/integration/whichbrowser/src/
   Model/Version.php
 *  254 | WARNING | Passing the $glue and $pieces parameters in reverse order to
   implode has been deprecated since PHP
    | | 7.4; $glue should be the first parameter
   and $pieces the second
 * Same in
    /Model/Primitive/Base.php
 * But at php website, it’s says the support for this function is not longer supported.
   So, is there plans to fix this? Or this doesn’t impact the plugin?

 * Hi,
 * I will update the WhichBrowser library in the next release, ’til then if you 
   do not need browser/device/os data, you can disable this feature and the error
   message will be gone.
