PHP Error during System Check

[1wraith1]

When trying to install the latest version of IPB, during the System Check phase, I get the following message:

Quote

The installer uses PHP sessions to store data, however PHP sessions are currently not working correctly on your server. This is an issue you will need to contact your host about. 5C348/1

Can you please assist me?

My server has the following spec:

Plesk 12.5.30 on CentOS 6.9, PHP version 7.0.19, MySQL 5.1.73

I think your MySQL version is very low

I'm running into the same issue right now trying to install a Dev instance of 4.2 (Edit: 4.1.19.4 is doing the same thing)

I've tried it on PHP 7.1, 7.0, and 5.6.

This is my 5.6 Sessions settings, but all three are otherwise identical. My sessions folder permissions are 777

It doesn't have anything to do with MySQL. It is a PHP check. 

 

But yes... he might hit a wall there too.  However, my MySQL version is 10.0.31-MariaDB and the install checker detects it incorrectly saying that my version is too low.

This is what i have:

So this is a PHP configuration problem, right? Or a permissions one?

I will try to cross-check with your phpinfo outputs to see what it may be wrong...

My output:

Regarding the MySQL, we updated it to 5.5.54

The most common issue here is that PHP cannot write to the define `session.save_path` make sure that it's writable.

I changed from plesk the session.save_path to /tmp and worked like a charm!

Thank you all for your answers!

Any other less common issues you know of that I can check?
