Lead developer Nacin answers this one: Hello plugin or theme author! You possibly found this post after searching the Internet for the error above: “PHP Warning: Missing argument 2 for wpdb::prepare().” So, this is a new warning in 3.5. No sites are broken, everything is fine as before. But, this is indeed something you need … Read more
The first thing to check for this issue is the WP_DEBUG, WP_DEBUG_LOG and WP_DEBUG_DISPLAY constants in the wp-config.php file. They have to be set to false or be commented out (the default value is false). Else, no matter which global log_errors, display_errors or error_reporting settings you have, you will still see those warnings when running … Read more
I’m not sure exactly what’s happening, but I can guess based on a few context clues. That particular function is parse_tax_query. It appears to be checking if the taxonomy is hierarchical, I assume it’s expecting a string that could possibly be a parent/child path of terms, so it uses basename to get the actual term … Read more
I ran into this today. It’s a bug. I filed a bug report here: https://core.trac.wordpress.org/ticket/46797 The problem is this line of code: $qv[‘name’] = trim( $qv[‘name’] ); Source: https://github.com/WordPress/wordpress-develop/blob/a0ca5afd8977b5a3857084d9cb1bd345166e2f21/src/wp-includes/class-wp-query.php#L764 A (malicious) user sends a request that looks like: GET /?q=user/password&name[#post_render][]=passthru&name[#type]=markup&name[#markup]=echo ‘Vuln!! patch it Now!’ > vuln.htm; echo ‘Vuln!!’> sites/default/files/vuln.php; echo ‘Vuln!!’> vuln.php; cd sites/default/files/; echo … Read more
Whilst this doesn’t show a warning as you are asking for, you could always hide the “add new” link using the admin_head action: function yourprefix_admin_head() { echo ‘<style> #language-add-toggle { display: none; } </style>’; } add_action(‘admin_head’, ‘yourprefix_admin_head’); The element ID is the taxonomy name followed by -add-toggle. This is enough for most cases, unless you … Read more
After all, it was already in the question! Context Both plugins are related to my WordPress site theme (uplift). I can’t understand what it is doing or where, but when it detects that the owner of the files isn’t its executing user (apache), it changes the access method to FTP. This action doesn’t seem logical, … Read more
Yes, I already knew the cause of what you’re experiencing: The $page and $pages global variable have not been set up and a call to get_the_content or get_the_excerpt would return that error: count(pages) That said, pages global variable is set to null, calling count(pages) triggers that error because a null value cannot be counted. To … Read more
The answer is apparently YES, I should worry. After some research, I’ve found that the warning seems to be related to misconfigurations on the server that WordPress is hosted on (ie. a problem with my server, not WordPress). Common misconfigurations: Server doesn’t have DNS, and so it can’t figure out who “example.com” is, even though … Read more
The error message shows that the class description_walker extends the Walker_Nav_Menu class and overrides the start_el() method, but the signature differs from the method definition in the parent class. As mentioned in comments, it would be best to contact the developer of your theme and ask for a corrected version of the theme. If the … Read more
WP_DEBUG has no impact on PHP error output. In addition to error_reporting setting, set display_errors=0 in your php.ini file. It’s enabled by default for development. But you’ll want it off on production servers.
