No what I am saying is your errors are strange like something is messing with the order in which data is being formatted for the query.
This error is different that your other thread as the issue is your category is empty and my question is why would it be empty ever. If you turn off your vb3 integration and do the same actions your doing to get the errors when vb3 integration is on and they dont happen with vb3 integration off that tells me you have some hack installed that causes this then we go on to the next step and try and diagnose things by turning on
vb integration and turning all hacks off and see if things work. If that works then you turn on hacks one at a time to discover which hack causes this issue.
I hope this clarifies the order in which to diagnose what the issue might be.
