Also, for this fatal error, can you remove that plugin from your website and install it anew from https://wpml.org/account/downloads/? Because it is possible that during some of the latest updates, not all of its files got updated properly.

nancyM	I was able to get the site back online by disabling the Yoast plugin. Now I don't think the wpml plugin is causing an issue: Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the woo-quickpay domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

Andrey WPML Supporter since 06/2013 Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+03:00)	You need to check if you are using the latest version of the Yoast plugin. If the fatal error still occurs, I need to see its entire content to understand where it comes from. The notices are harmless to your website. Each notice indicates the name of the triggering plugin.

Andrey WPML Supporter since 06/2013 Languages: English (English ) Russian (Русский ) Timezone: Europe/Kyiv (GMT+03:00)	Thank you for the details. Do I understand that it's okay now since you've switched the plugins? Or do you still need assistance?
