Migration 1.6 to 1.7 issue. Blank page not displayed due to a PHP error: Uncaught TypeError: Argument 1 passed to smartyClassnames()

[Nes]

Hi there,

Just upgraded my Prestashop 1.6.0.5 to 1.7.8.7 by using "1-Click Upgrade" module. After the migration process, a few minor adjustments were needed to access to the new back office. Now the backoffice is working properly without showing any error.

However, when I acces to the front end, I only can see a blank page. Checking the "error_log" file, I can see the following PHP error:

 PHP Fatal error:  Uncaught TypeError: Argument 1 passed to smartyClassnames() must be of the type array, null given, called in /home/szy3xy3c/devel.elrincondelcalzado.com/classes/Smarty/SmartyLazyRegister.php on line 95 and defined in /home/szy3xy3c/devel.elrincondelcalzado.com/config/smarty.config.inc.php:187

It looks like most of the contextual vars are undefined. The PHP error log also shows lots of "Notices" warning about this issue.

 I am using PHP 7.4 with all the needed extensions and parameters.

  Any idea of how to solve this problem? It looks like there is some kind of incompatibility, deprecated code and methods or settings that I need to adjust and, hopefully, everything will work... but not sure where to look at and how to fix it. Any help will be appreciated. 

Thank you!

Just a wild guess there, but maybe clean the cache?

Yes. Clear the cache in Var folder for the start.

Hi there,

Thanks for your replies. Unfortunately, deleting cache didn't work for me.. What it worked it was:

1- Creating a fresh installation of PS 1.7 in a new subdomain
2- Upgrade my PS 1.6 by "1-click upgrade" 
3- Swap databases. Fresh PS 1.7 database is using the updated database from my upgrades 1.6>1.7 version
4- Copy all my images in the fresh PS 1.7 installation
5- Normalize domines and delete old upgraded version and new fresh database

I am fixing some minor adjustments (modules..) but it looks good for now. 

I will post any important finding or highlight if any.

Cheers!
