Have been having problems posting to this forum. This is quick test to see if I can manage make it work. Paul feel free to delete this if you wish.
It worked! Let me know if you have any other issues. Will delete in a couple of days if all's working now.
No other obvious issues, I think. It would be good if you could check if there is a problem under Mobile Safari on an iPhone running iOS 11 or if that is just me.
Also, I did try and reply to the direct message you posted on the forum, but those replies are not visible to me. Did they get through?
