Hi

Thanks for contacting us. Allow me some time please. I need to talk about it with my team.

-Regards.

Hi Jérôme,

1. Yes, you can install SPPB 5.0.x on Joomla 3.10 and should work by now. At least worked on 2 websites that I tried in last week.
2. K2 component is not recommended anymore, but it's your choice to keep it or uninstall. You had many months, even years to migrate content from K2 to Articles. There are still extra extensions for that task. So do it before Joomla upgrade process.

Happy Bastille Day, I hope tomorrow will be calmer than recent riots events.

Hi dear Paul, thanks for your return. i don't find some component to replace K2. I can't migrate the site beacause i don't find this. The template NEWS 247 can't be use i J4! I try Vinazine Template with SPPB 4. For the moment it is ok. Thanks for your help great day best regards Jérôme
