Hello, I hope someone can help me.
I use the newsletter plugin and I like it. The problem started when I upgraded the wordpress version to 3.6-it. The plugin is disabled and I can’t see it in the plugins page. On the server there are all the files, but wordpress tell me that there is a problem with the files of the newsletter plugin.
What can I do for restart the plugin? I can’t lose the files because I have 12.000 subscribers for the newsletter…
but in this way I lose all my subscribers.
I remember you that I want preserve the subsribers detail, so I can’t simply delete the folder on the server and reinstall the plugin.
In what way can I do it? What is the folder, on the server, that I have to save and copy?
