Sharing the URL will not help. It's the website of my college and he checked on his computer and he doesn't have the issue, which I have on my computer, and which is:
In the editing mode, the field of the "SEO Title," which is part of the All in One SEO Pack in a WP blog, it says "19 characters," when the field is empty. If I write 10 chars, it will say 29 chars. It does not help no matter how I refresh, clear cache or whatever. This now happens in every old or new article I make, not only in the one, in which the problem started. It started when I copy-pasted a new SEO title in the place of the old one.
Another issue was, when I was on one public wireless network for a short time and I was editing one article draft on the same WP blog. I saved the draft, and the draft page (that only) has "adopted" the favicon of the wireless network homepage. Later it disappeared, but it just seems that some things glue to WP blogs I edit. Again, the problem seems to be in my computer, not in the blogs themselves.
