Tax Not Working Bad PHP Version.

[need2011]

I am using a very highly modified 1.7.4.4.  Last month my hosting company updated their cpanel where the lowest version of php was 7.2 my version of prestashop needs 7.1 so now the cart does not show taxes at checkout.  The site worked perfectly before the php upgrade.  I just migrated my site to a new host that uses the legacy 7.1 php.  It took 2 days just to get everything working but now the tax still does not work. 

The word tax shows up on the check out pages but it has all $0.00

I have searched to see if someone else had this problem but cannot find any answers.

Is there a module that I can reinstall?  Is there something that could be reinstalled to get this problem fixed?

Any help would be greatly appreciated.

Thanks

Have you tried with import taxes again?

Tax is in the core there is no module for it.  What would I import?  I would happily try.

Thanks
