I recently took over a site that is currently running version 1.4.4.1. It's a somewhat seasonal business, with the busy season upon us, so I'm concerned about jumping into an upgrade for fear of running into issues that could take me down for any length of time. Any comments on the risk/reward profile for jumping to the current version would be appreciated.
The known bug I'm running into concerns tax calculations where counties are involved. I've done a good bit of reading and found some threads referencing a code fix, and even a video discussing how to fix the issue by editing a query in county.php, but can't seem to find the actual code as it appears the bug tracker and forums have been upgraded over time.
I also found a reference to the fix being in SVN, here: http://forge.prestashop.com/browse/PSCFI-1622 which led me to GitHub.
When I look in GitHub, I see a 2013 version of country.php for 1.4 here: https://github.com/PrestaShop/PrestaShop-1.4/blob/master/classes/County.php
Is it a good idea to simply replace my county.php with this one, which includes what appear to be a couple of fixes to taxes and zip codes?
If not, can someone help me find the original code fix?
Thank you in advance for any assistance offered. I'm looking forward to getting more familiar with PrestaShop and the ecosystem around it. I'm not sure why it hasn't crossed my radar before now,
