If you are using Firefox 2, it is not enough to load your Yahoo! Mail Beta. Yesterday when I was trying to login to my beta account, it showed me error message saying that Yahoo! Mail Beta requires Firefox 126.96.36.199 or above. Therefore Firefox with 2 isn’t enough for Yahoo! Now what does that mean? Is Yahoo! running with the technology that as soon as the bugs are fixed, Yahoo! upgrades. I can still recall that the initial requirement for Yahoo! Mail Beta was Firefox 1.0 or higher / IE 5.5 or higher? And as the Firefox versions upgraded, Yahoo! also upgraded in similar manner.
As far as I can recall, Firefox 188.8.131.52 wasn’t more than just few security issues fixed.
Your PHP installation appears to be missing the MySQL which is required for WordPress.
I am surprised! A Yahoo! blog and such negligence :|.
