For some reasons I need to degrade WordPress version of a site (I understand that it is not a good practice to do and I can fall into many troubles by doing so) but I still need to do it for some reasons.
I want to degrade from 3.0 to 2.9. I tried to upload the wp-admin folder of WordPress 2.9 installation into my WordPress 3.0 site but it was unable to load all the files. I can not delete the upgraded version as it contains images of posts.
Is there any way to revert back to 2.9? Moreover, is there a plugin that can get this done?
Like you said, downgrading would be a bad practice and is not at all recommended. Please make a backup of your database before continuing, just to play safe.
It looks like you’ve only replaced
wp-adminfolder. WordPress updates are not limited towp-adminfolder.Try replacing
wp-admin,wp-includesand all those files in the root directory.Now clear your cookies and goto:
WordPress might ask you to upgrade your database and continue with it. After this, you’d be running 2.9 (hopefully).
