localhost error 500 xampp + wordpress beginner

[bert007]

Hi

Please find below my issue
I have install the last version of xampp and the last one of wordpress in local on my pc. At this stage I have got no issue. I can work on it.
When I try to use an older version of wordpress with the new version of xampp. I cannot and I have an 500 error.
Is it normal?
Do I have to to something else to use the older version.
I have just started courses and I am lost.
Thank you for your help.

Did you check that this older wordpress version is compatible with especially the PHP version XAMPP includes?
