It's more that reconstructing GETvars from url paths in RealURL skips empty arguments, which makes the reconstructed set of GETvars not matching the cHash being used to calculate. Something like that.

Best thing to do is setting „cHashExcludedParametersIfEmpty" to either „*" or the list of GETvars you expect to happen to be NULL sometimes.

Dear Stefan,
I skiped the null argument in my redirect, but there was no improvement The second suggestion is no option for me because there would be an effect for the global system. Thank you!
