dawan theme slideshow.js is having bug

Topic summary

A user is experiencing broken slideshows on their Dawan theme website after attempting to minify JavaScript files into a single file and attach it to theme.liquid. The issue appears to stem from slideshow.js code.

Troubleshooting Attempted:

  • Used ChatGPT to correct the code, but slideshows still broke after replacement
  • Shared the slideshow.js code (which appears corrupted/reversed in the post)
  • Referenced a Google Lighthouse performance score screenshot

Community Response:
A respondent clarified that the Google Lighthouse score shown is a performance metric, not an error—the site was functioning before modifications. They cautioned against:

  • Relying on AI tools like ChatGPT for complex theme modifications without sufficient technical knowledge
  • Making changes that could have significant negative impacts on the website

Recommendation: Revert to an original, untouched backup of the theme if available, as the modifications made may have introduced more serious issues than the initial performance concerns.

Hi,

I’m not sure if I’ve understood your problem correctly. It’s a bit unclear, but let’s start from the beginning.

  1. The Google Lighthouse score you received isn’t an error. It’s a metric that measures performance and SEO. Your website was functioning correctly before. The low score for the largest contentful paint element was likely due to the size of the element, which took a bit longer to load. This isn’t optimal for SEO and crawling, but it’s not a critical error.

  2. I’m unsure about the changes you made to your theme files using code. If you have a backup of the original, untouched theme, I’d recommend reverting to that. Relying on AI like ChatGPT for this kind of task without sufficient knowledge is not advisable. Even a small mistake, which AI can frequently make, can have significant negative impacts on your website. If you don’t have the necessary tools or expertise to fix these issues, the consequences could be even worse.
