Warning… wp-includes/taxonomy.php

  • Hi to everybody,

    I hope I’m in the right discussion. I’ve installed WP 2.7.1, a brand new installation, no upgrade, and I’m testing it on localhost. Now I found this strange behaviour. If I add/modify pages/posts as admin, everything works fine. If I do the same as Editor or Author I have the following messagge when I click on Update button:
    —-0000—
    Warning: Invalid argument supplied for foreach() in /var/www/wp-includes/taxonomy.php on line 1953
    Warning: Cannot modify header information – headers already sent by (output started at /var/www/wp-includes/taxonomy.php:1953) in /var/www/wp-includes/pluggable.php on line 850
    —000–

    When I edit the same page as ADMIN I have tthe following message on the top of the page:

    Warning: [username] is modifying this page.

    If I save the page again as ADMIN everything is fine.

    My running website is on WP 2.7 and doesn’t have this error. Should I downgrade the WP on localhost or is there a solution?

    Thanks to everybody
    Gabi

    This line
    /var/www/wp-includes/pluggable.php on line 850
    indicates the problem is related to a plugin. Did you by chance install something like MyCategoryOrder plugin, or another that modifies category order? It would be related to Category, Tag, or Link Category.

    If so, disable it and see if that resolves the problem.

    Deae All,

    thanks for your support.

    Following yours suggestions I disabled one by one all my plugins and found that the problem is with: User Access Manager.

    When I enable it I get the problem.

    Interpreting the error message on the base on the information in the link you sent me, I checked also the taxonomy file but it seems to me that there are not an excess of white space or similar.

    I will address my request to the plugin developer.

    Thanks again.

    What seems to be the problem?

    I use autoblogged too and I get this error:

    Is there a solution?

    Thanks!
