Hi,
What category slug should I use to get urls like: example.com/category-name or example.com/subcategory-name
I tried some variations and some don't work at all and some give duplicate id's like /category/96/96
If I use {CATEGORY_NAME} I get 404 errors for category pages.
If I use {CATEGORY_NAME}/{CATEGORY_ID} I get the duplicated ID like above.
If I use {CATEGORIES} if works for subcategories but I get 404 errors for category pages.

Just thought I'd share this as it took me a bit of time to figure out how to remove promo ads from the default Epsilon theme.
See photos.

This error shows up when I visit the website as a visitor
Because of unstable database that's the cause .

But I want to change the words , could it be in includes

when I ask chatgpt to fix this issue.

I have share head.php to chatgpt and then chatgpt rewrite this head.php  then some error  fixed..

Is this Head.php ok .. .and other thing how to fix this attached error Largest Contentful Paint element 5,100 ms
