URGENT! LOSIGN SALES! All dropdown menus load in for the first 0.5 seconds then dissapear

Technical Q&A

Topic summary

A Shopify store owner reports an urgent technical issue causing lost sales: dropdown menus in the header briefly appear for 0.5 seconds then disappear and become unclickable. The site uses the Influence theme, and the owner suspects a recently added sticky cart app may have corrupted the code.

Attempted Solutions:

  • Initial CSS fix (.site-header-sticky .site-header { top: 0 !important; }) didn’t work
  • A support representative suggested adding custom code before </body> in the theme.liquid file

New Issues Created:

  • Product pages now display incomplete text (“In stock - Sel” instead of full message)
  • Percentage discount badges appear incorrectly positioned on homepage and collection pages
  • Product image gallery broken: images display in a single row instead of clickable thumbnails on the left
  • Clicking thumbnail images no longer functions

Current Status:
The proposed fix resolved the menu visibility but introduced multiple new display and functionality problems across the site. The owner expresses concern about being unable to roll back changes after approximately 5 hours.

Yes it did work, but it did cause another issue.

Look at this product; https://zeenia.org/products/zeenia-hellstar-t-shirt-8948
2 things are wrong. You can see it says “In stock - Selling fast” like 15x under eachother.

and the percentage sign is also really weird on the home page. As in the percentage sign next to the discounted products which you will find if you scroll down a bit. For example at the “Hellstar Collection”
