My problem has now been resolved by the helpdesk people at IXWebhosting. I thought you might be interested to know how they did it:
I decided to make sure that fresh WordPress installation is working fine and installed it into http://being-in-voice.com/webblog/ (a new directory). Then I discovered that there is the same login issue as you experienced. So, I have searched the Internet and finally found a solution mentioned at the following pages:
In order to implement it I had to remove a code that is marked as dark green as you can see via http://core.trac.wordpress.org/attachment/ticket/12142/12142.diff from the folloeing pages:
After that I was able to access http://being-in-voice.com/webblog/wp-admin page using your login credentials:
Then I tried to implement the same solution for http://www.being-in-voice.com/blog/ but found that it is still not accepting passwords. Moreover, I found that it does not send passwords using "Forgot Password" link (in http://being-in-voice.com/webblog this option works fine).
According to this, I decided to create a backup of the following tables that belong to 'flloyd2_beingblog' database:
and restore them into flloyd2_flloyd2_webblogtest database I used for /being-in-voice.com/webblog/ blog.
If you check http://being-in-voice.com/webblog/ URL, you will see that it shows your blog as well as all the posts and commends. There is also no problem with admin login.
As she says, everything works fine, but we had to create a completely new directory to do it.
And my media files have pretty much disappeared! Some of them appear on the blog pages, but in the gallery there are a lot of broken links.
Hey ho. I will now set everything up again.
Thanks for all the offers of help. Much appreciated.
