I cannot access the plugins or appearance > themes. So outside of editting the content I cannot do anything with my wordpress installation. I have chedked the logs and get the below error:
PHP Fatal error: Cannot use object of type WP_Error as array in /wp-content/themes/x/framework/functions/global/admin/addons/class-update-api.php on line 86, referer: /wp-admin/plugin-install.php
I found a post that said I should backup and upgrade my version of X, but because I cannot access plugins, I cannot make the backup using the recommended plugin. Also, I am not sure how to upgrade the theme, because when downloading the latest version there is no supporting document of the steps to take to make the upgrade.
Any support greatly appreciated adn urgently required.
