Title: Installation and wp-db code bug? Last modified: August 19, 2016 --- # Installation and wp-db code bug? * [CallMeAndy](https://wordpress.org/support/users/callmeandy/) * (@callmeandy) * [17 years, 3 months ago](https://wordpress.org/support/topic/installation-and-wp-db-code-bug/) * My PHP is not good enough to be sure if there is a bug however the installation is not working if I embed the blog on my home page (It is working when in the default wordpress folder) thus: * main.php * ``` ``` * bodycenter.inc * ```

``` * and ./wordpress/index_mod.php * ``` ``` * The wordpress address in dashboard is /web/wordpress Blog address (URL) is / web which is where main.php resides. * The page fails to load the wordpress blog and on stepping through execution in PHPEd we come to the code * ``` if ( preg_match("/^\\s*(insert|delete|update|replace|alter) /i",$query) ) { ..... } else { $i = 0; while ($i < @mysql_num_fields($this->result)) { ``` * the step-through takes the else route as the query is a SET NAMES ‘utf8’ statement. Now I dont know what the @ prefix does on mysql_num_fields but ordinarily mysl_num_fields would expect a ‘resource result’ in this case $this->result is a boolean TRUE. And this is where the codes kick out an error saying “supplied argument is not a valid MySQL result resource” * I have not changed the code in any way or added any plugins etc, literally all i have done is change the relative locations between blog and dashboard in which I created one test posting.
