that IS the problem
i downloaded and installed bbpress today (i think this is the newest version) and then downloaded the 3 files from https://trac.bbpress.org/changeset/555/trunk?old_path=%2F&format=zip
but then: Fatal error: Call to undefined function: is_serialized() in [..] bb-includes/functions.php on line 364
if i update with newest file i get
Fatal error: Call to undefined function: is_serialized() in [..] bb-includes/functions.php on line 364
so what now? :X
