Support / Re: Unknown Error: AbanteCart ...
Last post by Basara - November 11, 2025, 02:59:03 AMHello.
The error you're seeing comes from the old PayPal Express extension (default_pp_express), which has been deprecated for years and is not compatible with AbanteCart 1.4.x. This extension should be completely removed from your store. Even if you are not actively using it, it can still hook into order or checkout events and trigger errors like the one in your log.
Please go to Extensions → Payments and make sure PayPal Express (default_pp_express) is uninstalled.
As for the customers who reported checkout issues, please ask them for more details so we can narrow down the cause:
What products were they trying to order?
What currency were they using?
Did they use any coupon or discount code?
At what step in the checkout did the problem occur: after selecting a delivery method, or at the payment selection step?
Which delivery and payment methods did they select?
These details will help identify whether the issue is related to a specific product, currency configuration, or payment/shipping extension.

Last post by irtsurpris - November 10, 2025, 08:55:32 PMI've been struggling with that overflow issue for ages — the last dropdown always went off-screen on larger menus. Your CSS tweak fixed it perfectly. Simple and clean solution!

Upgrade / Re: Upgrade Error 1.4.2 -> 1.4...
Last post by cartagan - November 10, 2025, 10:20:59 AMThanks. I just used the auto upgrade option. Do I just have to run the SQL in the link you provided?

Last post by abolabo - November 10, 2025, 10:14:46 AMLooks like you ran upgrade.sql twice.
If you do not have a database backup of 1.4.2, you can rollback database structure manually.
See https://github.com/abantecart/abantecart-src/blob/master/public_html/install/abantecart_database_upgrade.sql for details
