Have you tried disabling all plugins? See if problem goes away and if so re-enable them one by one to identify the culprit.
Firstly, disable LiteSpeed Cache, because the combined/minified CSS/JS might mess up the FontAwesome icon (which is used to show the arrow), also any caching must be disble before debugging.
Secondly, try disabling the ultimate-social-media-icons plugin, it’s the first suspect because it also uses FontAwesome icon which might be in conflict with the theme.
Thank you for your prompt response!
I tried removing these two, unfortunately didn’t help. I’ve also removed one by one plugins that might be causing it (almost everything that won’t cause my site/contents to crash such as Elementor and Yoast) but still nothing.
It’s not removing plugin one by one but rather start with disabling ALL plugins and see if problem goes away, this is to determine if the problem is from any of the plugins or faulty theme or WP core or else. If disabling all plugins makes problem goes away then we re-enable plugin one by one to rule out the culprit.
Anyway, it’s hard to help debug a live site that serves cached page (your site is using LiteSpeed cache), so I hope you follow the debug steps and find the plugin in conflict. Also please make sure to clear browser cache while debugging, sometime problem goes away but we still see cached page from our own browser.
Thank you it worked! The arrows are there, the culprit was ElementsKit Lite plugin.
I’m glad you finally got it working!
