Hi can you test the following, disable all Firewall rules. See if that solves your issue. If it does, start enabling one by one the Firewall rules until you find which one causes your issue.
Regards
That error actually doesn’t come from this plugin.
When I disable All In One WP Security plugin I can post comments ok.
When activate the plugin and disable all Firewall rules, I don’t get the error message (Duplicate comment detected; it looks as though you’ve already said that!) but the comment does not post properly – it shows up in my dashboard as from Anonymous, and there is no message text.
When I activate Firewall (tick all boxes in basic firewall settings) I get the duplicate error message when I post a comment.
Could this help identify the problem?
If the error doesn’t come from this plugin, could it be a plugin clash?
Many thanks
@salpilk in regards to your comment.
When I activate Firewall (tick all boxes in basic firewall settings) I get the duplicate error message when I post a comment.
Can you enable one by one the basic features in the Firewall Settings and at the same time carry out a test. This process will point to the feature that conflicts with your current setup.
I have tried switching the basic firewall rules on, one at a time. (Enable Basic Firewall Protection / Enable Pingback Protection / Block Access to debug.log File)
They all cause the duplicate error message.
When they are all switched off (but plugin is activated) the comment appears to send, but shows in dashboard as anonymous author and no message text.
I am posting comments on different post each time (as I wonder if I might be suspected as spam by posting lots of comments?)
