Title: Plugin does not activate (fatal error) Last modified: April 22, 2023 --- # Plugin does not activate (fatal error) * Resolved [RWK77](https://wordpress.org/support/users/rwk77/) * (@rwk77) * [3 years ago](https://wordpress.org/support/topic/plugin-does-not-activate-fatal-error/) * Hello, * I have a fatal error concerning the Mollie platform on my website. I tried the previous release 7.3.6 but got the same error. I can not activate the plug and therefore can also not check its settings. I tried deactivating and reactivating both the Mollie plug in as well as the Woocommerce plugin in different orders, since I found this as a proposed solution for similar problems but without any effect. On the Mollie backend everything seems fine. Any suggestions would be very much appreciated, here is the full error message: * **Fatal error**: Uncaught TypeError: ftp_nlist(): Argument #1 ($ftp) must be of type resource, null given in /domains/autoperforma.com/DEFAULT/wp-admin/includes/ class-wp-filesystem-ftpext.php:427 Stack trace: #0 /domains/autoperforma.com/ DEFAULT/wp-admin/includes/class-wp-filesystem-ftpext.php(427): ftp_nlist(NULL,‘/ domains/autope…’) #1 /domains/autoperforma.com/DEFAULT/wp-admin/includes/class- wp-filesystem-base.php(229): WP_Filesystem_FTPext->exists(‘/domains/autope…’)# 2 /domains/autoperforma.com/DEFAULT/wp-content/plugins/mollie-payments-for-woocommerce/ inc/utils.php(199): WP_Filesystem_Base->find_folder(‘/domains/autope…’) #3 /domains/ autoperforma.com/DEFAULT/wp-content/plugins/mollie-payments-for-woocommerce/mollie- payments-for-woocommerce.php(59): mollieDeleteWPTranslationFiles() #4 /domains/ autoperforma.com/DEFAULT/wp-includes/class-wp-hook.php(308): Mollie\WooCommerce\ mollie_wc_plugin_activation_hook(”) #5 /domains/autoperforma.com/DEFAULT/wp-includes/ class-wp-hook.php(332): WP_Hook->apply_filters(”, Array) #6 /domains/autoperforma. com/DEFAULT/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #7 /domains/ autoperforma.com/DEFAULT/wp-admin/plugins.php(194): do_action(‘activate_mollie…’)# 8 {main} thrown in **/domains/autoperforma.com/DEFAULT/wp-admin/includes/class- wp-filesystem-ftpext.php** on line **427** * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-does-not-activate-fatal-error%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Support [Syde Niklas](https://wordpress.org/support/users/niklasinpsyde/) * (@niklasinpsyde) * [3 years ago](https://wordpress.org/support/topic/plugin-does-not-activate-fatal-error/#post-16693203) * Hi [@rwk77](https://wordpress.org/support/users/rwk77/) * This looks like an issue related to your WordPress filesystem. This may be caused by an interaction with a third-party plugin. * Can you please try enabling a default theme like Storefront and disabling all plugins except for WooCommerce and then try again to activate the Mollie plugin to see if the error remains? * For more detailed instructions on how to safely perform a conflict test on your( staging) site, I suggest contacting the [Mollie Support Team](https://www.mollie.com/contact/merchants) directly.

I tried to deactivate all plugins one by one and activated a storefront theme. I still get the same message though, I have been reading a lot about issues with the Mollie plugin and will contact their help. If it can’t be resolved quickly I have no other option but to switch to another payment provider. * **Fatal error**: Uncaught TypeError: ftp_nlist(): Argument #1 ($ftp) must be of type resource, null given in /domains/autoperforma.com/DEFAULT/wp-admin/includes/ class-wp-filesystem-ftpext.php:427 Stack trace: #0 /domains/autoperforma.com/ DEFAULT/wp-admin/includes/class-wp-filesystem-ftpext.php(427): ftp_nlist(NULL,‘/ domains/autope…’) #1 /domains/autoperforma.com/DEFAULT/wp-admin/includes/class- wp-filesystem-base.php(229): WP_Filesystem_FTPext->exists(‘/domains/autope…’)# 2 /domains/autoperforma.com/DEFAULT/wp-content/plugins/mollie-payments-for-woocommerce/ inc/utils.php(199): WP_Filesystem_Base->find_folder(‘/domains/autope…’) #3 /domains/ autoperforma.com/DEFAULT/wp-content/plugins/mollie-payments-for-woocommerce/mollie- payments-for-woocommerce.php(59): mollieDeleteWPTranslationFiles() #4 /domains/ autoperforma.com/DEFAULT/wp-includes/class-wp-hook.php(308): Mollie\WooCommerce\ mollie_wc_plugin_activation_hook(”) #5 /domains/autoperforma.com/DEFAULT/wp-includes/ class-wp-hook.php(332): WP_Hook->apply_filters(”, Array) #6 /domains/autoperforma. com/DEFAULT/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #7 /domains/ autoperforma.com/DEFAULT/wp-admin/plugins.php(194): do_action(‘activate_mollie…’)# 8 {main} thrown in **/domains/autoperforma.com/DEFAULT/wp-admin/includes/class- wp-filesystem-ftpext.php** on line **427** * Plugin Support [Syde Niklas](https://wordpress.org/support/users/niklasinpsyde/) * (@niklasinpsyde) * [2 years, 11 months ago](https://wordpress.org/support/topic/plugin-does-not-activate-fatal-error/#post-16783251) * Hi [@rwk77](https://wordpress.org/support/users/rwk77/) * This error can only be the result of some customization on your site, either via a third-party plugin or the theme.
