Comment:

 Hi @betimademi

 The get_metadata function returns either a string, array or boolean. If it
 returns either a string or boolean and you call the `count` function it's
 going to error. So do a check in your conditional for `is_array` prior to
 your use of count to avoid this error.

 As well the Core Trac here is for development of the core and not support.
