@mercime I just tried deactivating all other plugins and reverted to all the default themes with the same outcome. I am not questioning the quality of the plugin whatsoever as I have heard many people using the plugin without issue.. but I am not sure what the issue that I am seeing may be.
Also i noticed on the plugin page that some others were asking about the compatibility with 3.4.2 so I am not sure if maybe someone else may be seeing the same issue that I am.
@mercime I have tried that plugin but it doesn’t seem to be working I am not sure if it is a compatibility issue with WP, but have posted on the restrict-usernames plugin support and am awaiting a response. I just though that maybe going the route of the registration form may be another option if it is even possible..
I am having the same issue and installed this plugin however it doesn’t seem to be working I think that there is an issue with the restrict-usernames plugin and WP 3.4.2. Is it working for anyone else?
