Sorry, but it does not work for me. I can not increase the width of the page through this setting.

Also, when I activate the HeadNFoot plug-in, I get an error: Fatal error: Uncaught Error: Call to undefined function mysql_query () in /home/eleon-s/eleon-s.ru/docs/wp-content/plugins/wp-headfoot/ library / base / data / table.php: 270 Stack trace: # 0 /home/eleon-s/eleon-s.ru/docs/wp-content/plugins/wp-headfoot/library/wordpress/data/legacy.php (14): bv48fv_data_table-> execute (‘\ nSELECT \ tcount (* …’) # 1 /home/eleon-s/eleon-s.ru/docs/wp-content/plugins/wp-headfoot/library/ wordpress / data / legacy.php (65): wv48fv_data_legacy-> update_done () # 2 /home/eleon-s/eleon-s.ru/docs/wp-content/plugins/wp-headfoot/library/wordpress/application. php (53): wv48fv_data_legacy-> update () # 3 /home/eleon-s/eleon-s.ru/docs/wp-content/plugins/wp-headfoot/index.php(11): wv48fv_application -> __ construct ( ‘/ home / eleon-s / e …’) # 4 /home/eleon-s/eleon-s.ru/docs/wp-admin/includes/plugin.php(1897): include (‘/ home / eleon-s / e … ‘) # 5 /home/eleon-s/eleon-s.ru/docs/wp-admin/plugins.php(172): plugin_sandbox_scrape (‘wp-headfoot / ind …’) # 6 {main} thrown in /home/eleon-s/eleon-s.ru/docs/wp-content/plugins/wp-headfoot/library/base/data /table.php on line 270

And one more question, tell me how to insert a mega tag into the header of the site, that it would be indexed by the search engine.

Thank you.
