Can't host a website on VPS (debian+vestacp+apache)?

Question

symfony

I put a clean image on the digital ocean (debian8 * 64)

500 error
[autoindex:error] [pid 8024] [client 198.148.27.26:40888] AH01276: Cannot serve directory /home/admin/web/mydomain.com/public_html/: No matching DirectoryIndex (index.html,index.cgi

Answer 1

Add sites through the Vesta panel itself, the same goes for the configuration.

Answer 2

Memory for the ptr array is not allocated at the beginning of the program, so there will be a memory access error in InitArray().
Incomplete condition at the beginning of the Function1() function - the option when index+del > size. The rest of the Function1() function must be completely rewritten, the whole logic of work is incorrect.

Answer 3

Why don't you allocate memory? What should your functions work with? Very original UB, will fall in a very very rare case. "+1" is not needed here.
This is not clear at all. Why links? And why are you walking through someone else's memory inside the function?

Answer 4

int* ptr = nullptr;
...
InitArray(ptr, size);

Your pointer is initialized to zero. He points to nowhere.
