Op basis van je stack trace lijkt dit een Composer autoloader probleem te zijn. En die zou weer veroorzaakt kunnen worden door een corrupte plugin installatie. Dus het advies is om de huidige ithemes-security-pro plugin folder te verwijderen en vervolgens handmatig het SolSec Pro 8.0.4 zip bestand te uploaden en uit te pakken (bijv via FTP of het Beheer panel van je hosting omgeving). * Ik hoor graag van je of mijn suggestie het probleem oplost. * Post edit: Wel raar dat meerdere mensen tegen hetzelfde probleem lijken aan te lopen. - This reply was modified 2 years, 6 months ago by [nlpro](https://wordpress.org/support/users/nlpro/). - This reply was modified 2 years, 6 months ago by [nlpro](https://wordpress.org/support/users/nlpro/). * [cuttlefishjones](https://wordpress.org/support/users/cuttlefishjones/) * (@cuttlefishjones) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17191242) * I have tried the above fix – removing the old installation directory and replacing it with a freshly unzipped plugin and still get a fatal error when to trying to activate it. * We are using w3-total-cache. Would that be having any impact on routing? * Versions: WordPress: 6.4.1 – php-fpm: 8.1.25 - This reply was modified 2 years, 6 months ago by [cuttlefishjones](https://wordpress.org/support/users/cuttlefishjones/). * [cuttlefishjones](https://wordpress.org/support/users/cuttlefishjones/) * (@cuttlefishjones) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17191366) * Is it possible to get the 8.0.3 version of the Pro plugin, the last one that worked to replace the current one until the root cause is found? * [casefixedwebdesign](https://wordpress.org/support/users/casefixedwebdesign/) * (@casefixedwebdesign) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17191379) * Same here for most sites I manage.

Our team has identified the issue affecting Solid Security Pro 8.0.4, and we are urgently working on a fix. If you have a recent site backup that you can use to revert to v8.0.3, please use that, but if not, please submit a ticket on our [helpdesk page](https://my.solidwp.com/panel/helpdesk.php)( you can mention my .org username, too) so we can give you a link for the correct zip which you can use in the meantime.Thank you all for understanding. * [cuttlefishjones](https://wordpress.org/support/users/cuttlefishjones/) * (@cuttlefishjones) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17191913) * I have re-installed the 8.0.4 replacement after downloading from my account and I can confirm that this has fixed the issue. Thank you. * Plugin Support [chandelierrr](https://wordpress.org/support/users/shanedelierrr/) * (@shanedelierrr) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17191956) * Hi everyone, I’m happy to inform you that the corrected ZIP is now deployed to the SolidWP Member Panel. Please grab the latest ZIP from your [SolidWP Member Panel](https://my.solidwp.com/panel/) account and install it on your site. And if you have reverted to an older version, updating directly from the WordPress plugins page should be good to go!We appreciate you letting us know about this, and feel free to reach out again if you have other issues! * [Ben Meredith](https://wordpress.org/support/users/benmeredithgmailcom/) * (@benmeredithgmailcom) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17192147) * Hey folks, * I’m the head of support here, and I wanted to personally weigh in. * As [@shanedelierrr](https://wordpress.org/support/users/shanedelierrr/) mentioned, we resolved the problem and are now working to ensure that something like this can’t happen again. * Here’s the short version: we were making some changes to an internal process that deploys updates late last night (US time) and we released changes to that process not realizing a typo actually ran the deployment for Solid Security Pro, but ran it incorrectly. * So while there wasn’t even a release of Solid Security Pro last night, silently the ZIP that users install by clicking “update” was errantly replaced with a half-built ZIP. That caused lots of problems. * As soon as our US-based dev team came online, we isolated the problem and fixed that ZIP file, so anyone who updated Security Pro since 9:19AM eastern US time has not experienced a problem. * So, in summary: **there is no issue in version 8.0.4 of Solid Security Pro.** There was a 7-hour period where the servers that supplied that version were delivering an unfinished ZIP. That’s been solved now. * This issue had no effect on Solid Security Basic, so the vast majority of users should see no issue here. * Rest assured we are working hard to ensure that issue can’t happen again. The integrity of your sites is the whole reason we are in business. * [casefixedwebdesign](https://wordpress.org/support/users/casefixedwebdesign/) * (@casefixedwebdesign) * [2 years, 6 months ago](https://wordpress.org/support/topic/latest-update-causes-fatal-errors/#post-17193249) * Thanks for the **update** . I have only a few plugins set to ‘trusted’ in mainwp and Solid Security Pro was one of them. Yesterday that resulted in about 30 sites going down 🙁 All is good now but will be more careful with auto updates in the future. Keep up the good work!
