[LuizSantos22]

Preconditions (*)

1. OpenMage v20.10.2
2. Cpanel / PHP 7.4

Steps to reproduce (*)

1. Download the ziped files
2. Upload it to the hosting, unzip it and install

Expected result (*)

1. Be able to create an account and add up address, etc...
2. Finish the checkout and place the order correctly

Actual result (*)

1. Im able to place the order, but it does not finish correctly because it does not save the customer address
2. This is the related to OM v20.10.2, because if I do the same with OM v19.5.3 it works just fine.

I have check it out with ChatGPT to see if I would get any reply to solve the issue but I was told it is related wtih "HTMLPurifier"

This is what it said: Error: Class 'HTMLPurifier_Config' not found

The error message indicates that the HTMLPurifier_Config class is not found in the Mage_Core_Helper_Purifier class. This is causing an issue with the customer address rendering in the checkout process.

I have tried to install it but it did not work
