php script permissions - need major help

[cathode]

Hello,
I am having a really hard time getting a script to run- specifically a Wordpress plugin. I have searched and read everything that has been posted here on this topic - and as a result know that folders should be set to 755 and php scripts set to 755 or 644.

But I have been trying every combination I can think of and cannot get a script to work. It returns a 404 error when I try to update the plugin options- which writes to the mySQL database.

The 404 error location (at .../wp-admin/options-general.php?page=wp_myscript.php) leads me to believe that this is a permissions thing- one php file is calling another one and one of them is writing to the database, but the server puts the kabosh on it because a file somewhere doesn't have the right permissions.

So I have been going thru my Wordpress admin directory, plugins directory, and tried every combination of 755 and 644 that I can think of. This has taken two days- so here I am

A 404 error would mean that the URL that you are trying to access does not exist. A 500 internal server error would display if the permissions were wrong.

That makes sense, but according to the URL, all of the files are in place, that I can see. one file is addressed via a php script though.

404:

http://www.mydomain.com/wp-admin/options-general.php?page=wp_myplugin.php

This page exists:

/wp-admin/options-general.php

And this page exists:

/wp-content/plugins/wp_myplugin.php

And- I just installed this plugin onto another server without trouble. I think now I'll go back and do a visual inspection of each file on the two unique servers... just to triple-check if they match up.

If you submit a ticket with the actual domain in question I can take a look. I certainly can't offer any promises though as this is well outside the scope of our support.

I have verified that all files are in place about 6 times now, and deleted /re-uploaded everything several times, changed the permissions of the whole WP-install (breaking other things in the process)... I just can't find the problem...

Look in the error logs to see if its calling for an alternate file.

Look in the error logs to see if its calling for an alternate file.

I was just going to suggest that. The "Error Log" in Cpanel can be invaluable in these cases. I had a similar problem, and it was a missing file that wasn't named in the error message written to screen. The error log showed what one it was.

[AndrewT]

This turned out to be a mod_security rule that was being triggered and WP was making this far more difficult by showing a 404 error when it wasn't.

Big props to Andrew for helping me on this. He's a master detective when it comes to this stuff
