When Matomo and Acymailing plugins are both activated. My WordPress admin pages show me a bunch of errors similar to skayw ones. * I contacted Acymailing, they tell me it has nothing to do with them… * Do you have more info? * Many thanks for your help. - This reply was modified 2 years, 9 months ago by [trouille2](https://wordpress.org/support/users/trouille2/).
