Log in or register, to view the original The source website https://tea.warrior.in.ua is: Joomla 3 The VirtueMart 3 There are dozens of additional extensions.I have updated the website https://test2.warrior.in.ua to (login and demo2 password): Joomla 4 The VirtueMart 4 Plus, it has updated about half of the required extensions.Everything that has not been updated has been disabled or deleted.Not seen any errors during the update.There are a number of problems that require a solution.A problem with SEF and VirtueMart.Before the update on the site was this: Screenshots of “do-obnovleniya-1” Screenshots of “do-obnovleniya-2” Now is so: Screenshots of “posle-obnovleniya-3” Screenshots of “posle-obnovleniya-4” If SEF Joomla is enabled, all VirtueMart pages (categories, goods, etc.)Not available (from the side menu and the category module to the main).If in VirtueMart you activate the “Strong Mode” option, then SEF works.Instead of this address: HTTPS://tea.warrior.in.ua/belyj-chaj/baihaiinchen-podrobnee Formed as follows: HTTPS://test2.warrior.in.ua/belyj-chaj/belyj-chaj/baihaiinchen-podrobnee That is, two times the category is duplicated - "belyj-chaj/belyj-chaj".Plus, if you go to any category from the left menu and click on that menu, then to the URLs of other categories in this menu will begin to add a part of the URLs of the category that you originally entered.2) If VirtueMart has the option "SEF for the link of the basket", then with the Joomla SEF included, a part of the address of the ordering page comes to the address of the product category.Here (http://forum.virtuemart.net/index.php?topic=148323.0), maybe I found some "explanation" of the situation: "We can assume, at least with j4.J4 has a lot of routing bugs.I don’t know the reason yet.Sometimes our router is just not called and cannot work.”As far as I understand, this is an explanation of one of the developers of VirtueMart.3) In the categories of goods does not work a change in the order of sorting (by increase or decrease).It is necessary to eliminate the problems and not to interfere with the work of everything else.It is extremely desirable to retain the possibility of updating CMS and extensions.I am interested in the price and time to solve these problems.
