I am running at least 5 blogs on my domain previously using WordPress 2.7.
Version 2.8 came along and I decided to upgrade my main blog which have running on the past 5 years on WordPress with no problems. The one-click upgrade worked without a hitch.
Yesterday, I tried to upgrade a second blog, another one which has been running for the past 5 years or so. After clicking on the one-click upgrade, disaster struck.
I couldn't log into my webhost (yaboo webhosting) control panel anymore, massive numbers of directories and files are missing (including some not associated with wordpress at all), and even my phpAdmin installation is wrecked.
Contacting yahoo support only reinstated the web control panel. I am now left with a broken webhost with 5 years worth of data missing (I should have made backups but thought that yahoo's snapshot function could have saved me -- it didn't seem to have done so). I'm still in the midst of requesting technical assistance from them.
The question is: is there a problem with the 2.8 upgrade? or is this purely a yahoo webhosting problem. I am on the verge of dumping their services if they are unable to resolve the issue.
