I really need help.
I tried to upgrade my WordPress 2.5.1 install with 2.6, and I followed all instructions to the letter.
I have upgraded previously (three times, actually) but this time the upgrade screen came up with:
Warning: require(/home/fhlinux152/p/psheads.co.uk/user/htdocs/wp-includes/plugin.php) [function.require]: failed to open stream: No such file or directory in /home/fhlinux152/p/psheads.co.uk/user/htdocs/wp-settings.php on line 228 Fatal error: require() [function.require]: Failed opening required '/home/fhlinux152/p/psheads.co.uk/user/htdocs/wp-includes/plugin.php' (include_path='.:/usr/share/pear/') in /home/fhlinux152/p/psheads.co.uk/user/htdocs/wp-settings.php on line 228
I'm really scared and i don't understand a word of what it says above. I reallyyyy need help. FAST!
