Title: Critical Error: Missing multiple wp-includes/html-api/ files Last modified: November 10, 2023 --- # Critical Error: Missing multiple wp-includes/html-api/ files * [amas008](https://wordpress.org/support/users/amas008/) * (@amas008) * [2 years, 7 months ago](https://wordpress.org/support/topic/critical-error-missing-multiple-wp-includes-html-api-files/) * Three of my WordPress sites are reporting critical errors after the automatic update (presumably to 6.4.1). The error is (copied from _error\_log_, but I have replaced the long path with …) * _[08-Nov-2023 10:53:31 UTC] PHP Fatal error: require(): Failed opening required‘/ home/…/wp-includes/html-api/class-wp-html-unsupported-exception.php’ (include\ _path=’.:/opt/alt/php74/usr/share/pear’) in /home/…./wp-settings.php on line 242_ * The directory _home/…/wp-includes/html-api_ only has the following 4 files; it does not include the “_class-wp-html-unsupported-exception.php_” file referred to above: * _class-wp-html-attribute-token.php class-wp-html-span.phpclass-wp-html-tag-processor. phpclass-wp-html-text-replacement.php * The _wp-settings.php_ file (updated on 8 Nov 2023) lists many more required files: * _require ABSPATH . WPINC . ‘/html-api/class-wp-html-attribute-token.php’; require ABSPATH . WPINC . ‘/html-api/class-wp-html-span.php’;require ABSPATH .

WPINC . ‘/html-api/class-wp-html-processor.php’; * The Github repository shows these new files under the 6.4.1 tag, including the“ _class-wp-html-unsupported-exception.php_” file that I do not have. * My only WordPress site that is still working (hbcc.net.nz) has not yet updated( version = 6.2.3, and _wp-settings.php_ has not been updated since April 2023). The hbcc.net.nz _wp-settings.php_ file lists only four files required in this _html-api_ directory (being the only four files I have in the site that is now giving the critical error), being: * _require ABSPATH . WPINC . ‘/html-api/class-wp-html-attribute-token.php’; require ABSPATH . WPINC . ‘/html-api/class-wp-html-span.php’;require ABSPATH . WPINC .‘/ html-api/class-wp-html-text-replacement.php’;require ABSPATH . WPINC . ‘/html- api/class-wp-html-tag-processor.php’ * I note that the GitHub 6.2.3 tag only shows these same four files, suggesting the extra files are new for 6.4.1. * I am running all four WordPress sites on GoDaddy under cPanel. I run WordFence, Easy Updates Manager, plus a number of other plugins * Why have my sites not downloaded what appear to be new files required in the_ html-api_ directory? * Can I just copy the files from the GitHub site under the “6.4.1” tag? * Thanks, * Andrew * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcritical-error-missing-multiple-wp-includes-html-api-files%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 4 replies - 1 through 4 (of 4 total) * [Manthan Kanani](https://wordpress.org/support/users/manthankanani/) * (@manthankanani) * [2 years, 7 months ago](https://wordpress.org/support/topic/critical-error-missing-multiple-wp-includes-html-api-files/#post-17190318) * Hello @[amas008](https://wordpress.org/support/users/amas008/), * The scenario is not listed here, So can you please write how I can generate the same critical bug? * Also, are you getting an error on restoring older sites? * Thread Starter [amas008](https://wordpress.org/support/users/amas008/) * (@amas008) * [2 years, 7 months ago](https://wordpress.org/support/topic/critical-error-missing-multiple-wp-includes-html-api-files/#post-17190447) * I did nothing to create this error; it was the result of a failed automatic update. I cannot access the site to try to restore it except by FTP; disabling plugins has no effect because the problem is in the core WordPress files. * Thread Starter [amas008](https://wordpress.org/support/users/amas008/) * (@amas008) * [2 years, 7 months ago](https://wordpress.org/support/topic/critical-error-missing-multiple-wp-includes-html-api-files/#post-17192790) * I have now checked the version.php file, and it shows at least one of my “critical error” sites as being version: $wp_version = ‘6.3.2’; * [psa47](https://wordpress.org/support/users/psa47/) * (@psa47) * [2 years, 4 months ago](https://wordpress.org/support/topic/critical-error-missing-multiple-wp-includes-html-api-files/#post-17346326) * You have to update the WordPress version. for that follow the following steps * **Please take the backup of your website folder from files manager first before proceeding to the following steps** 1. except for wp-content, .htaccess, and wp-config, delete all files and folders 2. download lates WordPress version 3. extract and open the downloaded WordPress. except for wp-content, copy all the files and folders 4. paste the copied files and folders in you website’s folder. 5. after that open wp-admin on the browser. instead of login page, they will ask to update the WordPress version. update it. then login to your wp-admin * Hope that’ll help Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘Critical Error: Missing multiple wp-includes/html-api/ files’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 5 replies * 6 participants * Last reply from: [psa47](https://wordpress.org/support/users/psa47/) * Last activity: [2 years, 4 months ago](https://wordpress.org/support/topic/critical-error-missing-multiple-wp-includes-html-api-files/#post-17346326) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
