I doubt if the issue is with the site. Having said that, keep in mind we just did a lot of research to find why some i-pad folks could not post and learned it relates to the software level. The forum software we use will support almost anything out there, but we know there are some vintages of software if will not support and we also know there are some programs used for creating a post that will act goofy.
Our web expert Joe has indicated we support almost anything out there but there are exceptions such as the older i-pad software that won’t work for posting. Is your software the latest version?
A word of warning to all: I have no clue about computer stuff so if you ask questions make sure they are simple ones. What I just said above is based solely on what I was told by our web guy Joe.
