I decompined this script of ioncube. The encripted script runs totally fine. But when I run the decrypt script the page gives me 500 Http error. The decrypt script is this:
<?php
/
$_X=base64_decode($_X);$_X=strtr($_X,'123456aouie','aouie123456');$_R=ereg_replace('__FILE__',"'".$_F."'",$_X);eval($_R);$_R=0;$_X=0;
?>

Line 122 : Again you forgot to start and end Single Line comment!
Line 159 : Don't know if you forgot to start comment or bad code!
Line 261 : Again forgot to start and end the comment!
Line 290 and 297 : Forgot to start and end the comment!
Line 291 and 298 : Syntax error! Looks like you wanted to start comment!
Line 339 : Syntax Error In MultiLine Comment! I am tired of writing again! :v
These are just Comment Errors!
There are multiple Variable Definition errors too! There are other Multiple errors! Check the full code once!
