I was running **Twenty Eleven Version: 1.2**. Yes, by update, I meant, new replacement theme. I should have tried updating 2011 theme when it failed with PHP8. I liked 2011, but now I am on 2020, so it’s all good. Thanks! * Forum: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) In reply to: [Need to update my Twenty Eleven theme to work with PHP 8.0](https://wordpress.org/support/topic/need-to-update-my-twenty-eleven-theme-to-work-with-php-8-0/) * Thread Starter [mathwriter](https://wordpress.org/support/users/mathwriter/) * (@mathwriter) * [3 years, 3 months ago](https://wordpress.org/support/topic/need-to-update-my-twenty-eleven-theme-to-work-with-php-8-0/#post-16505874) * Thanks for taking a closer look and trying it for yourself. But, are you mixing up 2011 vs 27? * That said, I did create a 2011 child theme that made 2 small edits to functions. php and footer.php. However, the error message (which I did not save), did not occur in those files. * The title is exactly what I did. I updated 2011 to 2020 theme and got my site to work with PHP8. - This reply was modified 3 years, 3 months ago by [mathwriter](https://wordpress.org/support/users/mathwriter/). * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [Exclude certain categories from main blog without Child theme?](https://wordpress.org/support/topic/exclude-certain-categories-from-main-blog-without-child-theme/) * Thread Starter [mathwriter](https://wordpress.org/support/users/mathwriter/) * (@mathwriter) * [5 years, 5 months ago](https://wordpress.org/support/topic/exclude-certain-categories-from-main-blog-without-child-theme/#post-13919186) * Ok, my code block worked for WP v3.2.1 Looks like it’s changed since. * ok, as for the function name, yes, I now see that it’s referenced by the add_action() * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [Exclude certain categories from main blog without Child theme?](https://wordpress.org/support/topic/exclude-certain-categories-from-main-blog-without-child-theme/) * Thread Starter [mathwriter](https://wordpress.org/support/users/mathwriter/) * (@mathwriter) * [5 years, 5 months ago](https://wordpress.org/support/topic/exclude-certain-categories-from-main-blog-without-child-theme/#post-13917013) * Also is it exclude_category() or exclude_category_home() ? * Forum: [Installing WordPress](https://wordpress.org/support/forum/installation/) In reply to: [Can I switch themes and not lose changes?

It says to NOT delete wp-content/ on my host, yet they are all empty folders. - This reply was modified 5 years, 5 months ago by [mathwriter](https://wordpress.org/support/users/mathwriter/).
