Nikola T.Staff24th Oct 2021 (16:27)Hello there,

Thank you for contacting the FastComet Tech Support Team.

I have checked out the website and I can see that it's fully reachable
+ on my end, as can be seen below:

> https://i.imgur.com/m7msFSe.png

I can see that you're attempting to run a Perl script.

Please note that your service was migrated roughly 2 days ago to a new
+er, more updated environment. And the Perl version was updated FROM -
+ 5.10.1 - TO - 5.26.3 - within the new environment

I would advise you to ensure that your Perl script's syntax is accepta
+ble by Perl 5.26.3, once you've ensured this and IF the script is sti
+ll not operational, please provide us with the following information:

1. If you are able to provide us with a STEP by STEP guide on how to p
+roduce the issue on our end so that we can investigate further, that 
+would be fantastic. Please also include any login details (URL, usern
+ame/email, password), IF they are necessary for the troubleshooting p
+rocess.

2. If possible, attach screenshots to your replies as well, so that we
+ can see how the case appears on your end or/and provide us with any 
+error messages that you might be getting.

Let me know if you need further assistance.

We are here to support you 24/7

Kind Regards,

Nick

Ivan IvanovStaff24th Oct 2021 (23:44)Hello.

Thank you for reaching back to us.

If I have understood your query correctly, you experience ' Internal S
+erver Error ' when accessing the following files:

> http://blackjackstory.com/0end5.cgi
> http://blackjackstory.com/0end6.cgi

I fixed the files' permissions, as well as reviewed all of the server 
+logs, however, I was unable to locate any error messages listed.

That being said, the 500 internal server error is still encountered wh
+en accessing your pages.

However, in order to make sure that we are both referring the same iss
+ue, please confirm that you are indeed trying, but you are unable to 
+access the above pages.

In case I have misunderstood though, please accept my sincerest apolog
+ies and elaborate further, so we can assist you accordingly.

Once your request and end goal have been clarified, we will thoroughly
+ review your case and assist you further.

Thank you for your understanding on the matter.

We remain available and at your disposal.

Kind Regards,
Ivan I.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
