Hey Bruno,
I have already tried disabling every mod on my site and still cannot find what is causing this problem, its a fresh 4.0.2 install, not upgrade from the 3.x series. I have checked and reverted every template, checked all file uploads, reinstalled product, maybe there is a issue with the suite, ergo; CMS and blogs.
I will try your solution, I need this MOD.
Thanks much.
