And then installed it again. This works but **please note that that you lose the settings and you have to reconnect the website to Mailjet.** * My second website I have done like this: 1. Downloaded the latest 6.1 2. Open the website which is broken in file explorer, FTP or through Plesk (f.e.) File browser. 3. Browse to the plugins folder /wp-content/plugins/ 4. Overwrite the **mailjet-for-wordpress** folder with the latest 6.1 and you should be back in the air * My question to developers of this plugin? Why not giving this plugin version 6.2 or 6.15? Updating would be way easier. * I have de same errror here.

Confirming [@bartheimenberg](https://wordpress.org/support/users/bartheimenberg/) solution where fully uninstalling then reinstalling works. * I am still coming across one issue: * Going to /wp-admin/admin.php?page=mailjet_settings_page always shows that the account is **not** connected. If I connect it everything looks fine. For example, I see the mailjet dashboard with buttons to manage campaigns, contacts, and view statistics. * If I navigate to a different page then go back it looks like its not connected again showing the Api/secret key in the text fields and connect your account button. It seems like its actually still connected though because if I directly access the dashboard page (/wp-admin/admin.php?page=mailjet_dashboard_page) I can still see the statistics. - This reply was modified 1 year, 7 months ago by [bcxdeveloper](https://wordpress.org/support/users/bcxdeveloper/). * Thread Starter [Thomas_bck](https://wordpress.org/support/users/thomasbrunck/) * (@thomasbrunck) * [1 year, 7 months ago](https://wordpress.org/support/topic/error-500-254/#post-18003595) * [@bartheimenberg](https://wordpress.org/support/users/bartheimenberg/) indeed, i just download the new plugin and upload files directly to FTP, no need to setting it up again * Plugin Author [Mailjet](https://wordpress.org/support/users/mailjet/) * (@mailjet) * [1 year, 7 months ago](https://wordpress.org/support/topic/error-500-254/#post-18003975) * Our previous release was made in fast way so we we apologize for that.
