Hashover v2 Installation Issues

[nootkan]

Been at this installation for a few hours now and can't seem to install it on a linux centos7.9 cpanel server. Here are the steps I followed:
1.downoaded hash2 master zip.
2. unzipped into my website folder on my computer
3. uploaded to my remote server inside a subfolder called comments
4. Filled out the secret.php file as per directions including creating a mysql database and smtp info
5. Manually filled in the database tables based on a thread in this forum - (done this before so I know what I am doing)
6. Added <script type="text/javascript" src="/comments/comments.php"></script> just before body tag as per hashover-v2/use document instructions
7. Added <div id="hashover"></div> where I want the comments to appear in my content page.
8. Uploaded page to server
9. Checked ownership and permissions: owner:owner folders:755 files: 644
10. Tried to browse to website/comments/admin/settings
11. Only getting a blank page - checked apache error logs, dom logs etc - there are no errors
12. Uninstalled and started over with the same result.
13. php version 5.6
14. Apache Version | 2.4.56
15. MySQL Version | 5.7.41
16. Architecture | x86_64
17. Kernel Version | 3.10.0-1160.80.1.el7.x86_6

I have set up lots of dbs and other open source scripts with no issues so I know I must be missing something simple. If you require anymore info please ask.

Thanks for your time.

Upgrade to a newer PHP version. I had the same issue with PHP 5.4 (old!), but it works with 7.4
