Steve Masraum offers some excellent tips/advice for isolating "where" the issue is. It's almost always on the client side ... but ...
Not knowing what happens on the server side (database flips/swaps etc), the server could be "hosed" if a db error occured while H&T was logging in, etc., and I had a few of those ... when making a post, etc. back when the site was mostly unreachable for several days.
Good luck ... Eric, thank you guys! Still lots of "things going on", but the efforts are noticed ....
And appreciated
