Webmail saving preferences problem

[rembrandt]

On one server (RH 9.0 PSA 7.5.1) people are complaining that they can edit their preferences (webmail says they are saved) but in fact they aren´t saved at all. I think there might be some problems with the tables Horde is using, any suggestions on how to solve this "nasty" problem?

I have the exact same problems... Horde preferences can't be changed!!!!!!!!!!

This is really BAD. I have clients complaining.

Any ideas?
