... problem error: fatal error: class 'thread' not found in. have include include_once or similar make work? have do??

your phpinfo shows have php thread safety disabled. need install version of php thread safe use pthreads. may or may not fix current issue though.

you may need copy pthreadsvc2.dll bin directory of web service well.

/etc/php55/fpm/ 

you're looking folder php.ini in it.

make sure php.ini file has line added:

extension=php_pthreads.dll
