And guess what? The website works (although poorly, without proper grid and not showing certain elements wothin the grid) UNTIL I switch om the Page Builder 2.2.2. Then, when I activate the PB, the site crashes including WP admin panel, so I have to go back to FTP and start the mess all over again. * I’ve spent hundreds of hours building the site and now it looks like crap due to the plugin unexpected failure.

The function siteorigin_panels_setting should be part of Page Builder. I’d suggest deleting the siteorigin-panels folder through FTP (in the wp-content/plugins folder), then reinstalling it. * Please let me know how this works out. * Thread Starter [fiorita](https://wordpress.org/support/users/fiorita/) * (@fiorita) * [10 years, 5 months ago](https://wordpress.org/support/topic/undefined-function-siteorigin_panels_setting/#post-6917312) * Hi Greg, * Thanks a lot for your response. I tried another solution which actually worked fine so far. I downloaded the WP 4.4.1. installation .zip folder and changed / wp-admin and /wp-includes through FTP. And I also reloaded Vantage theme I use. * I avoid deleting the PB plugin as the whole structure of the pages is corrupted when I reload it. * So, I guess the issue was with some corrupt files in WP and I wonder if it could be a malware or hackers’ attack. * Great plugin by the way. And theme. * With best regards, Fiorita * Thread Starter [fiorita](https://wordpress.org/support/users/fiorita/) * (@fiorita) * [10 years, 5 months ago](https://wordpress.org/support/topic/undefined-function-siteorigin_panels_setting/#post-6917359) * New problem here * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘ siteorigin_panels_basic_widgets_init’ not found or invalid function name in / www/doc/www.fiorita.cz/www/wp-includes/plugin.php on line 525 * PB was the ONLY switched plugin when the message appeared.

Yeah, from the sounds of things something was damaged with the files. Files shouldn’t be getting damaged like this, so it’s worth investigating the issue with your web hosts.
