the error trace follows:

any assistance appreciated.

nb: possible authentication issue. remote worker without access google console, must rely on boss swears has provided correct key !

i in fact rowanrh on github. after posting above - , not having received assistance - decided duplicate post on github.

i have resolved issue changing following php.ini settings:

1. i set (by uncommenting) extension=php_openssl.dll - necessary 'https' urls; ,
2. i set time-zone. google fussy times, might have affected outcome.

after testing in ide (i use phpstorm) restarted apache , !!
