I’m still stuck with this problem… I’ve uninstalled all my other plugins, but still whenever I activate the redirection plugin the blog breaks and I get this:

Fatal error: Call to undefined method RE_Database::_weak_escape() in /home/rock4172/public_html/digitalframeguy.com/wp-includes/wp-db.php on line 487

Anybody come across this one before?

@Andy – THANK YOU!

This has been driving me completely nuts. I have two blogs using this plugin. Both are WP 2.7 and both use the same theme and plugins. But redirection was only working on one *pulls hair out*.

I tried your suggestion and deleted redirection via the redirection options tab. It deleted the tables and deactivated the plugin. When I re-activated the plugin, all was working perfectly.

The only way I found to upgrade the plugin from a legacy 1.* installation successfully in the end was to run the upgrade to version 2.x in order to get at the Options page, then choose the Delete Redirection which removes the database tables and all legacy settings for the plugin. Then you can install the plug afresh and this time it will work, setting up the default modules and groups.

This leaves the problem of copying back in all the redirection data from the old version, which I failed to automate but could be done in theory with a bit of mySQL code or some command line programming with awk or grep.

I discovered that the import from csv file doesn’t work very well, even with a file created by exporting to csv from Redirection itself, but the import and export via .htaccess format does work OK.

I’ve been upgrading other blogs to WordPress 2.7 over the past few days and I’m closing in on the problem here. I’ve learned that this statement

“the latest version of Redirection doesn’t seem to work at all with WP2.7″

is incorrect. I don’t know what went wrong with the fresh install I reported above, but what I’ve discovered is that WordPress installations that had already upgraded the Redirection plugin to 2.0x worked OK when updated to WordPress 2.7 and then the latest Redirection, which is currently 2.1.4 and seems to be getting updated every few days at present.

So the problem I’m left with is how to convert the legacy Redirection database from the old structure to the new, a process that was handled automatically in early 2.x versions but no longer it seems.

Some clues:

There was an option to remove the plugin entirely in some versions.
There’s an import function but it only deals with formats from existing .htaccess file, a CSV file, or a Redirection XML.

I’ll probably have to do some tweaking of the mySQl table itself.

I am having a simlar problem — I have been using the redirection problem to make sure that people who my site feeds through old addresses (like wp-atom.xml instead of /feed/atom) can still get them. Now that no longer works, and I cannot see the settings page for redirection either

It sounds like this is one of the few items that didn’t transfer well to the new version of WordPress. One good thing is that this has reminded me of the Redirection Plugin, so that I can set it up if it appears to be beneficial to reroute people to 301 pages instead of 404 pages. I am sure you will have a functional setup in a short period of time.
