Why?

[Konstantinos]

Read the warning box and take a look at the example (specifically after the comment "Check, if the file is opened"): https://sampwiki.blast.hk/wiki/Fread

[AndreiWow]

But it worked before

fread(fhConnectionInfo, szQueryOutput);
fclose(fhConnectionInfo);

[Konstantinos]

It did because it always opened the file successfully. When fopen returns 0 though it will crash the server.
Plus make sure scriptfiles is both readable and writable (permissions).

Woops it was my fault for placing the folder in the wrong place xD
