OK, so I've been struggling for several, maybe even a dozen hours over the past few days, but I think I've finally gotten everything in decent working order.
It wasn't easy: I've looked at like, dozens of page online, opened up 4 support tickets, imported databases multiple times, made so many small little adjustments to things, backed things up, waited for uploads and downloads and converters and importers and UADASOIDUJAISOUDUASDIOA AAAAAAAAAAAAAAAAGGGGGGGGHHHHHHH IT WAS SUCH A PAIIIIIIINNN
but the old host was really, really poor, apparently had a 1-star rating according to what Blue Leafeon said, lol
wow they weren't kidding
so yeah, I upgraded to a slightly better host that should have more uptime and shouldn't randomly try to shut down my site and should hopefully actually respond to tickets with some small level of intelligence (though their responses so far weren't super helpful, but at least they were something of some small substance, lol)
Thank you for your patience and sorry that the site was up/down (mostly down) over the few days, and also sorry if anyone posted stuff or the like and it was lost: I know some shouts were lost but it couldn't really be helped as I had to delete the forums database and then try to re-import it from the back-up at least a couple times, so yeah.
