Issue End of script output before headers in FCGI mode

[Alireza Famili]

Hi

Here is my scenario: I have managed to use Zend Loader (latest version) for PHP 5.6.32 in FPM mode using this:
How to install Zend Guard Loader in Plesk

Now if I change modes to FCGI even the phpinfo script gives 500 error and logs shows:

-- (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
-- End of script output before headers​

Now I'm okay with FPM mode but I need a different php.ini for each web space and I think this additional directive only works in FCGI mode, correct? So I have to use FCGI mode.

Any ideas?
I had similar issue in XAMPP long ago and was able to get around it with FcgidIOTimeout value. But I tried addinf this to apache http directives with no luck

Any suggestions? Can someone at least point me to the right direction?
