I just ran the repair and optimise function in
vB and it threw up some errors with the pp_ tables:
pp_categories Check Error: Size of indexfile is: 1024 Should be: 3072
pp_categories Check Error: Size of datafile is: 0 Should be: 300
pp_categories Check Error: Corrupt
pp_categories
It looks like it fixed the problem and everything seems to be running with error messages.
