I knew this would be a mistake based on reading many times the turbid and obtuse upgrade instructions. I tried to follow each step. The result, for now, is a blank screen for http://7colorlagoon.com/blog1 and equally blank for blog1/wp-admin/upgrade.php and /install.php
Obviously I missed some step. I certainly don't want to go over the same process again from the same instructions. I have too many back up files -- from wp-backup plugin and manually. Which is the best to use to try to recover the blog?
Or the web host, PowWeb, has an installation service with a tempting button to "uninstall". If I uninstall everything and let them make an installation of 2.2 then what would I get from where to reinstall my content and whatever other files would be necessary?
The only step I can see I might have missed is that I left the wp-config file as instructed and have uploaded the new wp-config.sample.php file but not renamed it.
Any suggestions on how to get further with 2.2 or how to retreat to 2.1.3 would be appreciated. I have put far too much energy into making the change to a web host which was a mistake to invest too much more time especially when WP has promised the same hassle every few months. Disheartening!
Alternatively, should I be asking at PowWeb to figure out what I did wrong in installation?
