Upgrading Old Project - CSS Issue

Just opened a v2020 application in v2023. There are three immediately visible problems with the display that I’d like to fix.

  1. On the left, the new version has a huge left-hand column just showing the title and the logged in user. How do I get rid of this. (This app uses a horizontal menu, not one on the left.)
  2. The ‘Export to Excel’ button has lost it’s icon and is nearly invisible.
  3. The page selector and the records-per-page selector now both take up the full width of the screen which looks crazy. How do I fix this?

Thanks

Make sure you have generated all *.css and press Ctrl + F5 in your browser to reload the *.css files.

For some reason, it was not finding tempus-dominus.min.css
Re-generating didn’t cure it but after I ticked ‘Lowercase routes’ and regenerated again, it was ok.
