I’m getting this error on my site:
Fatal error: Uncaught TypeError: Argument 2 passed to SI_Estimates_Admin::filter_post_states() must be an instance of WP_Post, null given, called in …\plugins\sprout-invoices-biz\controllers\estimates\Estimates_Admin.php on line 286
I’ve deactivated all plugins apart from Sprout Invoices 19.9.2 and Sprout Invoices Pro 126.96.36.199. I’ve also swapped over themes to Twenty Twenty but still, the error persists.
My site is running WordPress 5.6 with PHP 7.4
Can you help please?
