Hello. How are you my good friends? How can I solve this problem that appeared to me when I wanted to install the script, this problem appears to me. Please help me overcome this problem.
If you need to activate the exec() function, then this is compromising on security features. Someone can execute malicious codes after activation.
However, if this is compulsopry to activate, then find this term in the php.ini and edit it, add it or uncomment it.
This install script checks certain prerequisites. If not found, it will give an error of 500. Nothing to be scared about. Simply fulfil the prerequisite and then you can proceed.
