Mmm...
It could be relative to your php environment.
Copy this php :

I think there is some version compatibility issue , what you think ?
by
everything enabled....

on the error_log any message ?

Check first that in your php.ini there is :
log_errors =On
by
Yes it is ON, But there is no error log generated
by
If you know any more Captcha , recaptcha is difficult for user
by
At least a warning should be displayed if something goes wrong in the processing..... (?)

Are you checking the right error_log file ? :-)

just to be sure, if you check on the phpinfo.php, the entry :
"error_log"
has a value or not ?

in your php.ini what's your error level ?
Check that it's for example :
error_reporting = E_ALL
by
Just as a test, if in your directory :
qa-plugin/q2a-captcha-antibot-master/

you rename the file "gothic.otf" to "__gothic.otf"

do you see something on the error file ?
by
Yes ,
Error :
PHP Warning:  imagettftext() [<a href='function.imagettftext'>function.imagettftext</a>]: Could not find/open font in /*/*/*/qa-plugin/q2a-captcha-antibot-master/AntiBotCaptcha.php on line 124

Are you on a shared host or on a vps ?
Do you have Ubuntu ? Which version ?
And which version of Apache ?
