I don't see some menus correctly

[Artix75]

Hello,
I am attaching two screenshots where you can see that the menus of the PERFORMANCE and CHOOSE LAYOUTS sections are not correctly displayed and therefore cannot be changed.

This problem also occurs in other menus.

I tried to enter with different browsers (Mozilla, Chrome Windows, Chrome Android, Edge) but the display doesn't change. 
Thanks

You modified your .css file

Go to /themes/your_theme/assets/css folder. Check custom.css - it seems you rewrote some .css styles of js files.

How to check it fast?:

1. Go to /themes/your_theme/assets/css/custom.css 

2. Copy all data (ctrl+a ; ctrl+c somewhere to keep it).

3. Delete all data from custom.css

4. Go to performance, clear cache.

If your menus are good after point 4, it seems you rewrite .css styles.

5. Restore your custom.css and then try to find error inside.

 

The same you can do for .js file in /js/ folder

You are using wrong PHP version - Prestashop is only compatible until PHP 7.2 not later
