1. Product Tabs issue
As you can see, the only results can be seen with ‘All’ not from the rest of the options.
2. Icons issue
You will also see that none of the icons are showing (search magnifying glass, arrow etc). The site is set correctly to https (Settings/General Settings) and I’ve cleared the cache on the browser and the website too.
Neither issue can be seen when logged in as admin. I’ve tested on Chrome, Edge and Firefox.
There is an issue with the 3rd party plugins. Please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists then keep the 3rd party plugins deactivated and share the WP admin login details of your site so I will check and give you a possible solution.
We have suggested deactivating the 3rd party plugins from the site to check whether any 3rd party plugin conflict with the theme or theme plugins. That is why to check the issue, you have to first deactivate the plugins then check the site with the theme’s default plugins.
