Hello,
1) Change permission to admin for our user because we are not able to check the backend settings of our theme or install cache plugin for example to speed up the site.
2) “menu alignment and some pages related to woocommerce store” – are you talking about mobile version only or also about the desktop? Could you provide links to pages where you have the problems and send screenshots of these problems using the Lightshot screenshot tool https://app.prntscr.com/en/index.html for better understanding?
Regards
