I've got a new link for a new page on my forum.
But I don't understand how to have the same design on this new page.
Thanks for your help.
My theme is based on Default theme
The new page without layout:
And the wished page layout :
Have a look at either of these plugins:
Unfortunately Basicpages plugin doesn't work. (plugin is not shown in the plugin list)
And Custompages plugin works but the example page is blank and I need it to understand how to customize my page.
It is a bit difficult for a newbie like me to debug
You will not find Basicpages in the plugins list because it is an "Application". Look at yourforum.com/dashboard/settings/applications
If you want to learn how to do something like that all by yourself, you can take a look at this example: https://vanillaforums.org/addon/howtovanillapage-plugin
Basic pages is an application, not a plugin, so needs to go into your applications folder. Then enable it via Dashboard - Addons - Applications
Yes it works !
Thanks a lot for help
