Take a look in the code for the plugin on this page: <a href="http://plugins.svn.wordpress.org/broken-link-checker/trunk/core/core.php" rel="nofollow">http://plugins.svn.wordpress.org/broken-link-checker/trunk/core/core.php</a></p> <p>Search for "blc_instances" and you will see the tables are related to that plugin.</p> <p>Search this page for why this host bans "Broken Link Checker":<br /> <a href="http://support.wpengine.com/disallowed-plugins/" rel="nofollow">http://support.wpengine.com/disallowed-plugins/</a></p> <p>My recommendation is to disable the Broken Link Checker. In any event, the errors are coming from that plugin, not Gravity Forms. </p> https://legacy.forums.gravityhelp.com/topic/database-errrors-on-upgrade-filters-doesnt-exist-instances-doesnt-exist#post-75620 Sun, 16 Sep 2012 02:59:23 +0000 DebC 75620@https://legacy.forums.gravityhelp.com/ <p>Hello, This problem is happening on every site, every upgrade I do for the past few months. It's past being ridiculous and annoying and I'm concerned I could wind up with crashed databases or having to recreate some lengthy forms.</p> <p>When it happens the site then within about 24 hours "bloats" and I get over the limit hosting notifications and find the site is very near or over limit for it's size and there have been instances the site is then down because it's exceeded it's hosting limitations and I have to go in and reset their hosting plan to cure the problem. </p> <p>This is one example of the error on upgrading the plugin. I've replaced the actual site name and the table name for security reasons:<br /> ________________</p> <p>WordPress database error: [Table 'sitenamehere.wp_tablenamehere_blc_filters' doesn't exist]<br /> SHOW FULL COLUMNS FROM wp_tablenamehere_blc_filters;</p> <p>WordPress database error: [Table 'sitenamehere.wp_tablenamehere_blc_filters' doesn't exist]<br /> SHOW INDEX FROM <code>wp_tablenamehere_blc_filters</code>;</p> <p>WordPress database error: [Table 'sitenamehere.wp_tablenamehere_blc_instances' doesn't exist]<br /> SHOW FULL COLUMNS FROM wp_tablenamehere_blc_instances;</p> <p>WordPress database error: [Table 'sitenamehere.wp_tablenamehere_blc_instances' doesn't exist]<br /> _________________<br /> Help would be greatly appreciated.
