This helped a lot, I fixed it. My code is now:
Content visible to verified customers only.
I have deleted the line:
Since it broke my template. I guess this is because I use the older RP 3.3 version and "reviewextras" is in my template already in a different place in the code.
I have also a different language file, so I used pros1 and cons1 and in the stylesheet also a different name to easier remember for what this addition was created. Otherwise I will forget it within 2 weeks
Thanks a lot!
