Because the problem is fully related to JAT3 (and HikaShop is not linked to that and it will never the case ; we do not declare or override Joomla core files). You have to put their system plugin before any other system plugin so the declaration of their JViewLegacy will be done correctly.

Anyhow, I hope this is a help for others. Check the JA T3 plugin. Change the order to first.

I have only learnt recently why hikashop was broken, and that was due to the order of the JA T3 plugin. I looked everywhere for the answer since this morning, then happened to read a French post which has a clue. Before that I had no idea. I came here to ask for your advice and see if anyone had the same problem. Forget speaking to JA T3 about this problem. Now that I have made this post in English, hopefully others will not need to ask you again as they have the answer.
