Newsletter has left of wordpress original sistem. It isn’t working now in the principal domain. Newsletter has left of wordpress original sistem since the programmer created a New folder (learning) that is outside the main root (institutoiseps.com/learning)
We need the system to work in both the original system and the learning folder.
Hi, the plugin can work only when installed in the newsletter subfolder of the wp-content/plugins. It’s not clear what the programmer did, but the plugin is not a standalone software that can be installed in a custom folder.
