  • I used the plugin from http://www.ryowebsite.com/?p=46

    I installed it correctly but i get this error on the “Category Visibility” page:

    WordPress database error: [Table 'wordpress.wp_categories' doesn't exist]
    SELECT * FROM wp_categories ORDER BY cat_name

  • Categories have changed. That plugin no longer works with WordPress. It says so in the comments on that very page, in fact.

    Also, if you look closely, you can find a link there that leads to a working version.

    [moderated: see new pastebin link below]

    I tried Beta9 and Beta10 from the site but they both still give me the same error.

    EDIT: its okay, i used MichaelH’s method.

    Thanks for your help guys! 😉

    Had to fix line 137 in category_vis-p7.php

    New pastebin link:
    http://wordpress.pastebin.ca/799362

    When i tried the first link you gave me that actually plin worked correctly but it wont let me hide anything it would just give me an error.

    Then i used the new link you gave me with line 137 fixed but now it shows this error on top of the dashboard.
    Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\wordpress\wp-content\plugins\category_vis-p7.php:1) in C:\xampp\htdocs\wordpress\wp-content\plugins\postratings\postratings.php on line 826

    Anyone gonna help?

    That error tells you that you left a blank line or space at the top of the plugin file.

    This is your clue:
    output started at ... \plugins\category_vis-p7.php:1

    The “1” is the line number of the file. Edit the file, remove the blank space at the top. The very first thing in a plugin MUST be <?php.

    Then why does it say something about my other plugin post-rating?

    Sorry im still new with php and stuff.

    b/c headers have to be sent before any text is. The first plugin generated an error (i.e. it sent text to the browser). When the post-rating plugin tried to modify headers, it couldn’t as a result of the prior error. First the first error, the second goes away.

    I checked the category plugin, there is no blank or emtpy line the top. It starts off as <?php

    Im still getting this error at the top

    Please Help! 🙁
