I also thought that, but how to solve it?
After updating the ACP told me to change multiple templates, and i did them all.
I suppose there it went wrong, but i can't roll back, becouse i dont know what template, and what else has been changed within that template.
I created a new style, but also in the new style it has the same problem!

Solved.
In vB 4.1.7 the code has been changed.
