PHP Warning "explode() expects parameter 2 to be string, array given" for multi-value country fields
Due to an unnecessary explode()
here, a PHP warning is thrown, when trying to save a multi-select country custom field with multiple values given.
The assigned variable $mulValues
is never used and possibly overwritten here with the same explode()
statement.
The line got added in this commit without an apparent reason, so it should be removed.
