500 internal server error prestashop 1.7

[Pharma1234]

Hello, 

 

I am facing 500 internal server error on prestashop 1.7

It all was sudden. Someone compromised my admin and DIR. and and put deface page in home/index.php that (You are hacked) 

 

I just edited the home/index.php page with default PS 1.7 index.php and removed the malware from my DIR. 

Then i just went to 500 internal server error. I have done all my best but it still exist. 

 

i tried to make .htaccess and replace /config/config.inc.php but all is same. 

most surprizing thing is when i edit home/index.php with simple HTML code, it load and reflect what i typed in home/index.php

 

dev mode also not working. when i set in defines value "true" 

everywhere 500 internal server error. 

 

Seems like issue coming from index.php. but not sure i am right. 

 

Please guide me what do to. 

 

my site down from 11 days,

 

Best Regards:
