Yikes! 404 errors ... help me please :) (4 posts)

    two part issue - both resulting in 404 error pages:

    1. Certain buttons on tinymce editor (Nextgen gallery and Cforms II) give small 404 error pages.

    2. The output of some plugins and scripts like this new one (simple maps) gives a 404 error code (/wp-content/plugins/simplemap/actions/location-process.php)

    Actions taken so far: Upgraded to latest wordpress version, installed fresh copies of wp-admin and wp-includes folders, deactivated ALL plugins (except the the one or ones that produce the error in #2 above). But none of this helps.

    I installed the same plugin (from #2 above) on two other wordpress installs - one on the same server as the one giving me issues - and it works flawlessly. Additionally, the two other WP installs mentioned aren't having the tinymce issue, either.

    Have I missed a troubleshooting step? I hope someone can assist me with this please. :)

    Why didn't you try deactivating them too?

    It could be a certain plugin combination that's causing your problems. Some plugins don't play nice with one another.

    Deactivate the lot. Or even better, reset the plugins folder by FTP or phpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems. If that resolves your problem, you know it's plugin-related.

    You might also want to try switching to the default theme to rule out any theme-related problems.

    because I had to test the plugin. By deactivating all the others except the one where the issue occurs, I thought I could see if there was a conflict with another plugin or plugins.

    In other words, plugin A is giving the error. No other plugins are active when it gives the error. Plugin A is NOT giving the error on two other installs. No other plugins are activated when testing plugin A. So my conclusion is the plugin isn't the issue.

    But I'll do as you said and reset all the plugins.

    Also, I did change the theme to the default theme and I'm getting the same issues.

    Thanks! Once I reset the plugins folder, I'll check back in.

    Hi Stephanie,

    Not sure if you sorted this out or not.

    I had exactly the same problem you described and after going around in circles for a few hours finally tracked the problem down so will post the solution here in case it helps anyone else.

    In my case it turned out to be suPHP doing its job.

    The default permissions in the cforms II plugin folder were insufficient to keep it happy.

    Counter-intuitively, relaxing the permissions makes things worse - they need to be tightened up.

    Make sure all troublesome plugin files and directories are only writeable by the owner i.e strictly 644 and 755 respectively.

    This fixed things up fine for me with WP 2.8.4 & cformsII 10.6

    Best Regards,

    Phil
