Alex, whatever needs doing, needs doing & u fortunately one of the core things missing from web systems these days is compatibility for migration. Just like the old days everyone wants to sell you into their fleece you for life software option.
I’ve lost a few sites ove4 the years & eventually gave up, due to lack of time & future compatability, as in if I rebuild it, in a couple or 3 years I’ll have to do it all again
So I just gave up. I like this site, as I hate the way so many forums have leapt on the FB garbage. I don’t & won’t do FB, so hope you manage to find a cunning solution to our upgrade requirements.
And thanks for all the hardwork you put in, it is appreciated.
