My blog gets down when i published a new post so i am checking every plugin. First, i suspected Google XML Sitemap plugin probably it is creates an infinite loop or something. After i worked on it, found some mistaken urls on sitemap then fixed it.
After that i run debug mode on sitemap plugin and saw that all page filled with these errors below. Actually it seems all these are warnings.
Undefined index: 9646 in /home/admin/domains/....../public_html/wp-content/plugins/page-links-to/page-links-to.php on line 205. line 205 is that if ( $links[$id] ) $link = esc_url( $links[$id] );
Posts which i used Page Links To Plugin are inside sitemap, so there is no problem with it. But i suspect when i published a new post, Sitemap plugin found out these error then crush my database. May be creating new mysql connections then
I saw the creater of plugin Page Links To Mark Jaquith is around. So could you give me a hint or something, can that be the problem?
