Hello – I have just worked out that it is to do with the microsoft firewall which must have been updated recently and is now blocking me uploading anything to wordpress. I now need to work out how to fix the firewall so I don’t need to turn it off completely, but I will mark this as fixed anyway.
Thanks for your post. I read through the master list first and did all the usual things. So did the chap from godaddy. I also spent quite a long time reading through posts on this site as well as others before I posted and really couldn’t find issues where it worked on one computer but not another. I don’t think it is a problem with my site as much as a problem with the pc.
