I am unable to get one of my add-on domains to show up in my browser. I am able to log into the WP-Admin Dashboard, and all posts, pages seem to be there, BUT there are warning messages all over the place like this on the Dashboard:
Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/neilccom/public_html/copingwithpanicattacksinfo.com/wp-includes/theme.php on line 513<
I have LOST the theme that I had previously installed. There is now no theme at all and when I try to re-install the theme, I get warning messages like this:
Warning: Invalid argument supplied for foreach() in /home/neilccom/public_html/copingwithpanicattacksinfo.com/wp-admin/includes/theme-install.php on line 492
Then when I tried to reinstall the theme I got another warning:
Downloading install package from http://wordpress.org/extend/themes/download/twentyten.1.1.zip…
Unpacking the package…
Installing the theme…
Could not create directory. /home/neilccom/public_html/copingwithpanicattacksinfo.com/wp-content/themes/twentyten/
Theme install failed.
This all happened after I had used FileZilla to upload some videos for use on my site, which I was subsequently unable to embed. Maybe I uploaded them to the wrong place and this has upset the applecart. When I view the files on my website via FileZilla, I notice that My add-on domain is in two places, the additional place being under a directory called WWW. Is this correct?
I am really worried now as I have just spent time pinging search engines that I have just updated the site and they won't even be able to access it.
It has just occurred to me that my WordPress installation may be corrupt. Is this possible? I can access & edit all my posts and pages through WP-Admin (which is also where I can see all the warning messages) but get a blank screen when trying to preview anything.
If it is corrupt, can I reinstall it without losing all my data? I have copies of all my posts and pages input in a text file.
I would be grateful for any help.
