Hello,
1) Set product title limit – 2 lines https://prnt.sc/23pnyua Check the product alignments now.
2) Banner hover effect “Slide right” increases the width of the banner image and it causes a difference if other banners use another hover effect. So, I changed Slide right to Zoom effect. Check now.
3) What exactly is wrong with the mobile version? I don’t understand problem here https://prnt.sc/23po6qz
4) Contact your hosting provider and ask them about reports of the queries that use a lot of CPU on your site. Provide us with these reports to find out what exactly is the reason of the issue.
Regards
