I gave you the link to the codex that walks through what you need to do to move a site from one host to another.
you got the reply you did from me because of this,
"ps. I only uploaded various versions of WP to eliminate that as a cause, which it did, because I'm getting the same wp-admin "White Screen of Death" on versions 2.6-2.8. "
I cant tell you, more matter of factly than I already did, that that's a cause of problems, not a viable troubleshooting technique.
but hey -- you sounded like you knew better, so what the hell.
as for the rest:
Sorry, Ive never played WOW and I dont have a penis.
For what's it worth, Ive learned to pick my battles around these forums -- there are countless threrads on here where people went off 1/2 -cocked, didnt know what they were doing, spent more time writing than reading, and ended basically with nothing after they were done.
Those are the people that dont read, dont follow the links theyre given, dont stop to think before they do something, and .. oh they also have attitudes.
Im not going to apologize for saying the obvious - you sound like you dont know what you are doing. Thats not me being mean spirited or arrogant -- its just an observation
You didnt need to change hosts, wordpress runs just fine on siteground.
Youve apparantly spent timne doing stuff that doesnt really amount to much with the uploading of the files and what not.
Not the way I would have handled things but okay.. thats your deal, so go for it.
Now youre here, and your moving the site. MySQL errors are googlable... Ive given you the link to the codex. Instead of taking my remarks personally- slow down, dont answer questions that you dont know the answer to, and instead of sounding resentful over the fact that someone (me) knows more than you -- take advantage of it and ask articulate questions if you have trouble.
Support is a 2 way street. Asking for "commiserating" or general help isnt going to illicit much.
