I sent a reply to my webhost's reply, and when they replied to that reply (still with me? LOL) it seems that they actually thought that I meant that I was having issues accessing my website. So the answer quoted in the above post, is telling ME what to do and not YOU.
In their reply they told ME...
If you still experience any problems accessing it, please try cleaning up your browser cache, resetting your internet connection or restarting your computer.
... so perhaps if YOU did that, it might help YOU!?
Or of course they advise that I can upgrade to their premium account, so that all these little issues should be made less frequent or obsolete. Obviously that would be a very last resort on my part, as so far all of my websites have been freely-hosted.
