How to update the WordPress version manually?

[Israeltimi]

Hi, love this repo!

I installed it already and i can see there is a newer wordpress version. I tried to replace the wp-admin and wp-includes folder (with the latest versions of these folders) but i have this error code

Fatal error: Uncaught Error: Call to undefined function wp_is_valid_utf8() in /tmp/wp/wp-includes/formatting.php:2287 Stack trace: #0 /tmp/wp/wp-includes/class-wp-taxonomy.php(378): sanitize_title_with_dashes('category_name') #1 /tmp/wp/wp-includes/class-wp-taxonomy.php(290): WP_Taxonomy->set_props('post', Array) #2 /tmp/wp/wp-includes/taxonomy.php(532): WP_Taxonomy->__construct('category', 'post', Array) #3 /tmp/wp/wp-includes/taxonomy.php(63): register_taxonomy('category', 'post', Array) #4 /tmp/wp/wp-settings.php(513): create_initial_taxonomies() #5 /tmp/wp/wp-config.php(157): require_once('/tmp/wp/wp-sett...') #6 /tmp/wp/wp-load.php(50): require_once('/tmp/wp/wp-conf...') #7 /tmp/wp/wp-admin/admin.php(35): require_once('/tmp/wp/wp-load...') #8 /tmp/wp/wp-admin/index.php(10): require_once('/tmp/wp/wp-admi...') #9 {main} thrown in /tmp/wp/wp-includes/formatting.php on line 2287

Hi @Israeltimi -- I think you're on the right track and maybe missed some files in the update? That was my first thought and it looks like others (outside of ServerlessWP) have encountered the same issue, for example. I am behind on updating the included version and am open to suggestions on how to make it easier!

I'll give it another try and revert back. Thank you
