Question: All pages that have session\_start() on the page have suddenly stopped loading and it's been working for years like this. Even the host is unsure of what to do, looking for advise.

A sample test page with the following code also failed:

```
error_reporting(1);
if(!$_REQUEST['disable']=="yes")
{

session_start();
}
echo "hello";

```

If I call the page without passing the parameters ?disable=yes the page doesn't load, it just hangs processing

The site is hosted along with 2 other sites on the server, the other 2 don't have any issues, it's just this one site that has all of a sudden started acting like this [no code has been changed on the site for 2+ months now].

Answer: 
Looks like you'll need a combination of [MIME::Base64](https://metacpan.org/module/MIME%3a%3aBase64) and [MCrypt](https://metacpan.org/module/Mcrypt).
There is a package in cpan .. MCrypt
