.htaccess "304 not modified" ?page_id=xxxx error

Trying resetting your permalinks.

Dashboard / Settings / Permalinks

Take note of what the permalinks are now.

Reset to Default and update.

Then set back to what they were at first and update.

Behind the scenes this forces WordPress to rewrite a number of things. This often (but not always) resolves permalinks issues.

that actually made it worse. Now, none of my custom post types can be accessed.

I am getting a not found page for all of them.

Something is wrong then as resetting permalinks by itself can’t make it worse when you reset them to what they were in the first place.

What is in your htaccess file?

Do you have a database backup from before you upgraded?

reinstalling wordpress seemed to fix the custom post type issue.

Here’s the .htaccess file. deactivating and deleting wpsupercache doesn’t seem to do anything.

Also, it seems on the pages that I’m linking to using “?page_id=xxx”, it’s actually a “301 moved permanently” error I’m getting the first time, then a 304 error on subsequent refreshes.

Yeah, I have a backup, I actually already tried to go back to the previous install, and it didn’t help either.

Everything was working fine until you upgraded. So something changed…

For debugging purposes I’d disable SuperCache and remove its code from htaccess file. Go back to plain simple WordPress until you find out what is wrong.

Next thing might be disable all plugins and turn them back on one by one to see if the latest upgrade broke a plugin’s code.

Supercache disabled and removed. all references to it removed from wp-config and .htaccess. disabled all plugins.

Still no change. Man, this is frustrating.

try resetting your permalinks again

no luck. It seems I need to do something more significant here.

Any ideas of how to proceed?

Have you tried:

– switching to the Twenty Ten theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

It’s not a theme issue, I switched themes with the same result.
