Plugin could not be activated because it triggered a fatal error. — WordPress

When installing or upgrading a plugin in WordPress, you may get a message like this: Plugin could not be activated because it triggered a fatal error. The specifics may look something like this Fatal error: Access level to WPsite_Firebar_List_Table::get_table_classes() must be public (as in class WP_List_Table) in /xyz/wp-content/plugins/codecanyon-9861906-firebar-notification-bars-for-wordpress/admin/model/list-table.php on line 460 The error is likely due to an outdated version of WordPress. Upgrade to the latest version and your issue will hopefully be resolved 🙂

Regenerate thumbnails error on WordPress [SOLVED]

Recently I switched to a new WordPress theme and subsequently encountered some image thumbnail issues. Here is the specific error I received when regenerating thumbnails: function (){if(l){var t=l.length;(function i(t){x.each(t,function(t,n){var r=x.type(n);”function”===r?e.unique&&p.has(n)||l.push(n):n&&n.length&&”string”!==r&&i(n)})})(arguments),n?o=l.length:r&&(s=t,c(r))}return this} This was particularly frustrating, because if a custom size is not available then WordPress will use the FULL size image even for thumbnails. This of course results in slow page times and wasted bandwidth 🙁 The solution Thankfully, after a little checking it appeared to be a simple permissions

The best custom taxonomy plugin for WordPress? [SOLVED]

I checked out a bunch of custom taxonomy plugins for WordPress. When it was all said and done my favorite plugin was: Custom Fields and Custom Post Types Management http://wordpress.org/plugins/types/The complete and reliable plugin for managing custom post types, custom taxonomy and custom fields. While it is a little hefty at ~6.8MB after uploading, it does the trick and is fully compatible with the latest WordPress version. Woot! 🙂

[Err] 2006 – MySQL server has gone away Navicat/WordPress [solved]

Recently I tried upgrading to the latest version of the WordPress Download Monitor plugin. It did not go well 🙁 Thus, I tried to revert from a backup made using Navicat. Unfortunately, the restore would fail every time while trying to import my wp_posts table (a pretty important table!) I tried exporting the backup to a SQL dump and importing that. No luck. Finally, I tried resolving the actual ‘MySQL server has gone away’ issue itself and I had success. This tip

WordPress comment pagination and 301 redirects

I recently enabled paginated comments on my WordPress blog. Later I decided to disable pagination and just go for the regular ol’ a single comments listing on each post (regardless of how many comments there are). After the chance I was a bit worried about duplicate content, but thankfully when I unchecked the ‘break comments into pages with…’ option from wp-admin -> settings -> discussion WordPress automatically took care of redirecting! Here is the example: http://www.jdhodges.com/blog/dreamweaver-document-too-large-copy-past/comment-page-2/ auto redirects to http://www.jdhodges.com/blog/dreamweaver-document-too-large-copy-past/

Permalink Updates on WordPress

For a very long time this post’s permalink URL would have been: http://www.jdhodges.com/2013/07/permalink-updating-wordpress/ But now it is: http://www.jdhodges.com/blog/permalink-updating-wordpress/ I made this adjustment primarily because an old URL like this one: http://www.jdhodges.com/2012/05/exede-wildblue-satellite-internet-review/ Even if the actual content was updated the URL made it look like it was only updated in 2012. The new permalink structure is shorter and more relevant, so far I love it! 🙂 However, one should exercise caution when doing this type of update as it can wreak
