Turn Off Auto Update for Single Plugin

Question

I have a plugin that I know I never want to update. I am aware that this is NOT best practice, but in this case it must be done. Is there any way to stop WordPress from prompting me to auto-update a particular plugin (but still alert as normal for all other plugins).

Answer 1

you place this in your theme's functions.php

//Disable update notification for individual plugins - see my example of plugin block-spam-by-math-reloaded as to how to use this function
function filter_plugin_updates( $value ) {    
unset( $value->response['block-spam-by-math-reloaded/block-spam-by-math-reloaded.php'] );    
return $value;
}
add_filter( 'site_transient_update_plugins', 'filter_plugin_updates' );

T31os's answer was right: Increase the version number inside the plugin's main file.. eg. 99.9 ... and also make that same change inside the readme file for good measure(though i don't think that's actually required).. – t31os

Answer 3

Or you just rename it so it is 'not' the same plugin.
You need to rename not just the folder but also in the readme and plugin header.
