Thanks Steve. I was just about to reply. Unfortunately, that didn’t work.
I’ve set up a basic test install (just WP and SP) and opened it to guest posting, and I’ll try and get a few friends from around the world to test it. I’d appreciate it if anyone here could also give it a go for me.

If it posst okay, I’ll know because I’ll see the post, If it doesn’t, can you please let me know, either here or there.
I want to eliminate all doubt that it’s something to do with my computer or ISP. I need multiple tests because it does occasionally work for me.
