Re: WordPress MU 2.8.1 Released
I have had no luck at all trying to upgrade from 2.7.1 to 2.8.1
Here are the steps I am following:
1. backup all files and db – done
2. deactivate all plugins on the main blog
3. remove all plugins from the mu-plugins folder
4. delete wp-admin and wp-includes folders from server
5. upload all new 2.8.1 files to the server
Then when I try to reach any page on the server I get a 500 error which is as follows:
PHP Fatal error: Call to undefined function wp_clone() in /website.net/wp-includes/cache.php on line 380
The only thing I can do at this point is to delete all the new files I uploaded and replace them with the old 2.7.1 files…
I have tried this 4 times so far with no luck. I have made absolute certain that all the files are properly overwritten, but still end up with the error.
Is there a solution to this problem, or am I the only one with it?
I’ve read the upgrade docs, and as far as I can tell I am not missing a step, so I’m really stumped here…..
my buddypress install is NOT on the primary blog, so I did not have to change the theme. It is a wp standard theme on the primary blog
