Yes, You can either delete the post tag code from php file or you can use css to hide the tags, Whichever you choose make sure you make a back copy of that file or make changes in a child theme.
I apologize for my lack of code knowledge, but could you give me a step by step guide? Also, will these changes be lost when a theme update is done?
Yes, these changes will be lost after theme updates. So please do not make any changes in the original file of the theme. You can create a child theme instead if you haven’t created yet. Reference: https://codex.ww.wp.xz.cn/Child_Themes
Simply add the following code to your child theme’s style.css and it will hide all the post tags.
.entry-footer .tags-links,
.entry-footer .cat-links {
display: none;
}
I want to hide this tags? help me.
