Hello
sidebarright and sidebarleft
In last
Joomla Blank template we fixed this
If you update the template and I simply reinstall it, then my CSS file would no longer be included
For that, BEFORE ANY Updates - we advice to our clients: "Please do backup" - with that you lost nothing important.
In Our Template we have possibility add custom.css file - we have't so file in our template - but we use it - if it exist - so you may add your custom styles to this file - so all yours style will exist after update
Regards
