I am trying to install the Reaction theme from Themeforst and when I try to activate OptionTree I get the following fatal error: * Warning: require_once(/services/webpages/t/h/therogermag.com/public/WP/wordpress- content/plugins/services5/webpages/util/b/a/baggio.site.aplus.net/therogermag. com/public/WP/wordpress-content/plugins/option-tree/functions/functions.load. php) [function.require-once]: failed to open stream: No such file or directory in /services5/webpages/util/b/a/baggio.site.aplus.net/therogermag.com/public/ WP/wordpress-content/plugins/option-tree/index.php on line 26 * Warning: require_once(/services/webpages/t/h/therogermag.com/public/WP/wordpress- content/plugins/services5/webpages/util/b/a/baggio.site.aplus.net/therogermag. com/public/WP/wordpress-content/plugins/option-tree/functions/functions.load. php) [function.require-once]: failed to open stream: No such file or directory in /services5/webpages/util/b/a/baggio.site.aplus.net/therogermag.com/public/ WP/wordpress-content/plugins/option-tree/index.php on line 26 * Fatal error: require_once() [function.require]: Failed opening required ‘/services/ webpages/t/h/therogermag.com/public/WP/wordpress-content/plugins/services5/webpages/ util/b/a/baggio.site.aplus.net/therogermag.com/public/WP/wordpress-content/plugins/ option-tree/functions/functions.load.php’ (include_path=’.’) in /services5/webpages/ util/b/a/baggio.site.aplus.net/therogermag.com/public/WP/wordpress-content/plugins/ option-tree/index.php on line 26 * [benjibuls](https://wordpress.org/support/users/benjibuls/) * (@benjibuls) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-optiontree-after-upload-plugin-could-not-activate/#post-2375447) * Hi Derek, I’m having the same error above on a fresh copy of WordPress 3.3.1 I’ve tried re-installing a fresh copy after deleting the plugin from both the“ Install Plugins” tool inside wordpress and manually downloading the ZIP from wordpress.org, neither worked. Any ideas why this would be? * [benjibuls](https://wordpress.org/support/users/benjibuls/) * (@benjibuls) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-optiontree-after-upload-plugin-could-not-activate/#post-2375448) * Have discovered the issue, the plugin is using an old method to define the plugin directory and url global vars. In the plugin index on line 18 & 19 change the following: * Replace: * ``` define( 'OT_PLUGIN_DIR', WP_PLUGIN_DIR . '/' . dirname( plugin_basename( __FILE__ ) ) ); define( 'OT_PLUGIN_URL', WP_PLUGIN_URL . '/' . dirname( plugin_basename( __FILE__ ) ) ); ``` * With: * ``` define( 'OT_PLUGIN_URL', plugins_url( '', __FILE__ ) ); define( 'OT_PLUGIN_DIR', plugin_dir_path( __FILE__ ) ); ``` * And then the plugin behaves. I guess wordpress have finally deprecated the old methods. * [benjibuls](https://wordpress.org/support/users/benjibuls/) * (@benjibuls) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-optiontree-after-upload-plugin-could-not-activate/#post-2375449) * OK, so good and bad news… * **Good news** The plugin doesn’t cause a fatal error when activating now. * **Bad news** It doesn’t work properly as none of the settings changed within an OptionTree based theme stick. Nothing gets saved. * Any help would be greatly appreciated, or I may have to discontinue using OptionTree all together, sigh.
