Hello,
I encountered this issue
New installation on a PS 1.7.8.8 with 2 languages
When modifying a category of the blog, if by mistake a space is put at the end of the 'Category link rewrite' field
Registration keeps space well (which does not seem to be the case in the case of a prestashop with a single language)
The display of the category in FO gives an error of the type "Too many redirects"
