With 1.4.2, no problems but after update, appear error and popup doesn’t work :
<b>Warning</b>: filemtime(): stat failed for /home/clients/xxxxxxxxx/xxxxxxxxx/wp-content/plugins/popup-notices-for-woocommerce/src/assets/dist/frontend/js/vendor/micromodal.min.js in <b>/home/clients/xxxxxxxxx/xxxxxxxxx/wp-content/plugins/popup-notices-for-woocommerce/src/php/class-modal.php</b> on line <b>91</b>
Thanks for reaching out. I apologize for any inconveniences you may be experiencing.
I have tested the plugin on my end, but it seems it is working properly. Could you please ensure you are using the latest version of WooCommer and WordPress? Also just to be sure, you are using the version 1.4.7 of the plugin, right?
