Thanks a lot for the quick response.
I had a chat with the techies on the afternoon and I was told that my site was hacked (or what) earlier in December and that caused the issue.
I have two problems with this explanation:
– They told me that this happened in the first half of Dec. If so, I don’t get why this happened at that time.
– Anyhow, I should be able to reach the WP dashboard somehow
