This issue has been resolved. The problem was the version of PHP I reduced it from 8.4 to 7.4 and the demo installed
The fix to this problem is to update the server to run php version 5.6 or higher to process .php files.
I too have the 500 server problem. When I upload the woocommerce plugin while the enfold theme is active I get the 500 error. So I turned the woocommerce plugin off uninstalled the enfold theme and reloaded the woocommerce plugin which installed fine. Then I reloaded the enfold theme and as soon as I activated I get the 500 error. How to fix this problem?
