Usually such issues are specific to site configuration or server configuration/resources and that would need to be checked. * If you have access to some server PHP error log (or could ask your host to look into it) and you could share such log – entries from about time when this happened– it could help diagnose the issue. * As for rollback, simplest way is as follows * 1. access your site via FTP, cPanel “File Manager” or similar way and go to “/ wp-content/plugins” folder 2. delete “forminator” folder from there entirely( it will not remove any form data from site, only the plugin itself) * If Forminator update took the site down, site should get up after that (note: if there’s any server-side cache, you may need to purge it additionally) * You should be able to login to the site then just fine. * 3. then you can download previous version of plugin from this page (form at the bottom): * [https://wordpress.org/plugins/forminator/advanced/](https://wordpress.org/plugins/forminator/advanced/) * 4. and, finally, simply install it via the “Plugins -> Add new -> Upload” option in your site’s back-end. * This way you would retain all the forms and data that was already there. * Kind regards, Adam * Thread Starter [Muette](https://wordpress.org/support/users/muette/) * (@muette) * [2 years, 8 months ago](https://wordpress.org/support/topic/update-bug-5/#post-17111402) * Thank you, have managed to rollback to previous version 1.26 which works fine. However, I tested this twice, both times 1.27 caused a critical WP error – and there were no changes to the rest of the environment in the intervening period so we are still unable to use 1.27. I have looked thru PHP error logs – nothing– and have put in a support request to the hosting company. May I reiterate also, I was not the only one who experienced this today – I noted another person with the same issue. * Thread Starter [Muette](https://wordpress.org/support/users/muette/) * (@muette) * [2 years, 8 months ago](https://wordpress.org/support/topic/update-bug-5/#post-17112912) * Thanks for the instructions. * I replicated the error and this points firmly toward a mismatch between your latest version and WP functions.php line 5905: * “Fatal error: Uncaught Error: Call to undefined function php_uname() in D:\Inetpub\ vhosts\DOMAIN\wordpress\wp-content\plugins\forminator\library\mixpanel\class- mixpanel.php:151 Stack trace: #0 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-content\ plugins\forminator\library\mixpanel\class-mixpanel.php(64): Forminator_Mixpanel- >super_properties() #1 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-content\plugins\ forminator\library\class-core.php(128): Forminator_Mixpanel->__construct() #2 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-content\plugins\forminator\library\class- core.php(68): Forminator_Core->__construct() #3 D:\Inetpub\vhosts\DOMAIN\wordpress\ wp-content\plugins\forminator\forminator.php(377): Forminator_Core::get_instance()# 4 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-content\plugins\forminator\forminator. php(106): Forminator->init() #5 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-content\ plugins\forminator\forminator.php(84): Forminator->__construct() #6 D:\Inetpub\ vhosts\DOMAIN\wordpress\wp-content\plugins\forminator\forminator.php(505): Forminator:: get_instance() #7 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-includes\class-wp-hook. php(310): forminator() #8 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-includes\class- wp-hook.php(334): WP_Hook->apply_filters() #9 D:\Inetpub\vhosts\DOMAIN\wordpress\ wp-includes\plugin.php(517): WP_Hook->do_action() #10 D:\Inetpub\vhosts\DOMAIN\ wordpress\wp-settings.php(495): do_action() #11 D:\Inetpub\vhosts\DOMAIN\wordpress\ wp-config.php(86): require_once(‘…’) #12 D:\Inetpub\vhosts\DOMAIN\wordpress\wp- load.php(50): require_once(‘…’) #13 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-admin\ admin.php(34): require_once(‘…’) #14 D:\Inetpub\vhosts\DOMAIN\wordpress\wp-admin\ upload.php(10): require_once(‘…’) #15 {main} thrown in D:\Inetpub\vhosts\DOMAIN\ wordpress\wp-content\plugins\forminator\library\mixpanel\class-mixpanel.php on line 151 * Notice: Function is_embed was called incorrectly.

It seems that, the php_uname() function is disabled by your host (either or purpose – assuming some security risk or just by oversight) the “php_uname()” function on the server. Most likely that happened upon PHP update/switch from 7.x to 8. x. * That doesn’t mean that there is a bug in Forminator but rather that it’s a server/ hosting specific issue and so far it’s quite rare. * However, we care a lot about compatibility so I have reported it to our Forminator Team already and our developers will look into it to see how they can modify our code so it would no longer need that function (or at least didn’t fail if it’s not available). * I’m not able to give ETA on this as it’s a fresh discovery and needs to be fully investigated by developers, fixed and then also tested by QA team before release but they’ll work on it and fix would be included in one of future releases. * As for now, you could ask your host to see if they could allow the php_uname() function for you or, if they refuse, stick to previous version of the plugin until the fix is released. * Kind regards, Adam * Thread Starter [Muette](https://wordpress.org/support/users/muette/) * (@muette) * [2 years, 8 months ago](https://wordpress.org/support/topic/update-bug-5/#post-17113419) * Thank you very much.

However, there’s no ETA, I’m afraid. * Meanwhile, if the hosting support can’t help with enabling _php\_uname_ function, you can try a workaround with defining it in a PHP snippet. * Please save the following code in as a PHP file, e.g. php-uname.php, and upload it to _/wp-content/mu-plugins/_ directory: * ``` php_uname('s') . ' ' . php_uname('r') . ' ' . php_uname('v') . ' ' . php_uname('m'), 's' => 'Windows NT', 'n' => 'Windows', 'r' => '5.1', 'v' => '5.1 build 2600', 'm' => 'x86' ); return $uname[$mode]; } } ``` * This should make it run as a [must use plugin](https://wordpress.org/support/article/must-use-plugins/). * Let us know if there’s still any issue! * Best Regards, Dmytro * Thread Starter [Muette](https://wordpress.org/support/users/muette/) * (@muette) * [2 years, 7 months ago](https://wordpress.org/support/topic/update-bug-5/#post-17159256) * Thank you Dymtro I will try that.

However, I can’t guarantee that _php\_uname_ function can be completely omitted, or provide any ETA at this point, I’m afraid. * Please let us know if the above PHP snippet helped to make it work on your end. Your feedback can help our devs to make the right decision, (e.g. use a similar solution in the plugin). * Best Regards, Dmytro * Plugin Support [Nithin – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport11/) * (@wpmudevsupport11) * [2 years, 7 months ago](https://wordpress.org/support/topic/update-bug-5/#post-17176926) * Hi [@muette](https://wordpress.org/support/users/muette/), * Since we haven’t heard from you for a while.
