I have a blog that is using WordPress version 2.7 and it has become corrupted due to the use of Slickr's use of the function fopen, which is disabled on my host's server. I had been using Slickr for months and was only when I activated NEXTGen plugin that this problem arose. I've disabled both now but makes no difference the damage has been done.
After many hours of struggling with the web host they have wiped their hands of the issue and told me I need to reinstall WordPress as simply restoring the database didn't work.
So I have looked through the Codex and forums but can't find anything on this:
How do I install the latest version of WordPress if I already have a corrupted and older version installed?
i.e., Do I have to uninstall the corrupted version of WordPress first?
Or do I install straight over the top by following the standard installation Codex instructions?
Will my back up from an older verison of WordPress be able to be restored to the new installation?
Or do I need to install 2.7 first and then upgrade to 2.7.1?
I have already tried the automatic upgrade to 2.7.1 and it failed. Message gven was:
Downloading update from http://wordpress.org/wordpress-2.7.1.zip
Unpacking the core update
Could not create directory: /public_html/website/blog/wp-content/upgrade/core
It managed to write a few files to the wp-content/upgrade/core folder before failing so it doesn't appear to be a permissions issue with the folder.
Any advice on where to go from here?
