I just found out that when I deactivate Buddypress and Youzer and use the sign-in from my theme everything works fine. WordPress takes me to the “ugly” registration page and even sends me an email which I need to activate.
I turned on WP_Debug as you suggested and checked the error log (debug.log) which I had to create as there was no such file in the wp-content directory. According to a “How to use wp debug with wordpress” tutorial, I changed the file permission to 777. However when I downloaded the file, it was empty.
Switching over to another theme didn’t give any results. Even with the twenty something theme I could fill out the fields on the register page, however, still no new user is being created in the database.
Just deactivated the plugin and tried registering a new account in another browser. The new user is not being created in the database. Don’t know whats going wrong here. Youzer is not the culprit 😉
Anybody an idea? I checked the pages inside the bp themes folder and registration.php and activate.php are there. Don’t understand why no user is being created in the database.
