I can’t reproduce that on a clean install. What other plugins are you using?
I deactivated all plugins but still can’t delete the blacklisted email. I uninstalled the plugin, then I checked the database. The blacklisted email still was there in the wp_options table (I have another prefix). I deleted it and re-installed the plugin again, then I blacklisted the same email. The result is the same: I can’t remove the blacklisted address (it is only one in the list). I tried to change the theme, the result is the same.
Can this be an Internet provider related issue? I had in the past some problems with his server settings.
Add a second one (like spammer@example.com) and then delete the first one… I have a weird thought.
OK, I added the second email spammer@example.com, updated the options and successfully deleted the first one. Now I can’t delete the last email (spammer@example.com).
Okay I know why and it makes a little bit of sense to why I didn’t test that. When on earth would your list ever be empty if you were using it?
My bad. I’ll see if I can fix that.
It’s OK. I will wait an update. I have an empty list just because I wanted to test your plugin before to really use it :).
How would you test it without using it? Anyway, it may be a bit. WP 4.3 is due out today and this is lower priority for me.
This will be fixed in 2.5, which will be released later today.
Sorry about 2 months… I blame … puppies.
