I am trying to:
Update to most current versions of toolset plugins.
I first tried to update all Toolset plugins. Site crashed. WordPress emailed error below. I then restored a backup. Tried updating one at a time. Started with Views. Crashed again. I then restored.
An error of type E_COMPILE_ERROR was caused in line 10 of the file /xxx/xxx/xxx/public_html/wp-content/plugins/cred-frontend-editor/application/controllers/compatibility/wpml/integration/forms_translation/legacy.php. Error message: Declaration of OTGS\Toolset\CRED\Controller\Compatibility\Wpml\Integration\FormsTranslation\Legacy::register_strings($form, $form_data) must be compatible with OTGS\Toolset\CRED\Controller\Compatibility\Wpml\Integration\FormsTranslation\Base::register_strings(WP_Post $form, $form_data)
This error still happens in the latest release, it should have been investigated, when reported by @margep6083
Now it brought down all sites where Toolset updated automatically or where people updated CRED and Access.
