Title: Plugin Causing Fatal Error on Website. IONCUBE encoder error php 5.5 Last modified: August 31, 2016 --- # Plugin Causing Fatal Error on Website. IONCUBE encoder error php 5.5 * [Kindly Thrive Support](https://wordpress.org/support/users/compassionateveg/) * (@compassionateveg) * [10 years, 1 month ago](https://wordpress.org/support/topic/plugin-causing-fatal-error-on-website-ioncube-encoder-error-php-55/) * Out of the blue yesterday, my site required me to upgrade to a newer version of ION cube. Here was the site error. * Site error: the file C:\…\wp-content\plugins\seo-alrp\php\admin\registration. php requires the ionCube PHP Loader ioncube_loader_win_5.5.dll to be installed by the website operator. If you are the website operator please use the ionCube Loader Wizard to assist with installation. * I had received this error once when I built the site. Not a huge deal so I upgraded. Then I immediately received a white screen of death. No error, just a white screen instead of my site. I have dealt with these issues before but this time I had nothing to go off of. I have shut the site down and then removed all plugins. I still had no site. Anyways, I finally was able to get an error and it points at your software. * [30-Mar-2016 18:32:23 UTC] PHP Fatal error: The file C:\…\wp-content\plugins\ seo-alrp\php\admin\registration.php was encoded by the ionCube Encoder for PHP 4 and cannot run under PHP 5.5 or PHP 5.6. Please ask the provider of the script to provide a version encoded with the ionCube Encoder for either PHP 5.3 or PHP 5.4 or PHP 5.5. in Unknown on line 0 * I have found 2 other support articles in here which never were responded to. Please reply with a solution. I am going to keep working because my non-profit’s website has now been down for over 12 hours! * [https://wordpress.org/plugins/seo-alrp/](https://wordpress.org/plugins/seo-alrp/) Viewing 2 replies - 1 through 2 (of 2 total) * Thread Starter [Kindly Thrive Support](https://wordpress.org/support/users/compassionateveg/) * (@compassionateveg) * [10 years, 1 month ago](https://wordpress.org/support/topic/plugin-causing-fatal-error-on-website-ioncube-encoder-error-php-55/#post-7223540) * In the end I removed SEO-ALRP and still had issues. I found out that when I installed a new copy of WordPress yesterday for another website, Windows Server installed PHP 5.5 which my main site is not compatible with. So over the course of 7 hours I completely uninstalled php 5.5 and reconnected 5.4. I had to also restore a backup of all of the site files. For some reason it would still not work after going back to 5.4. That was a very frustrating issue. I sure wish WordPress had an error log system that would tell me what was going on when white screen of death happens. * [nhatdang_daisu](https://wordpress.org/support/users/nhatdang_daisu/) * (@nhatdang_daisu) * [9 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-fatal-error-on-website-ioncube-encoder-error-php-55/#post-8253604) * i have **Seo ARLP Premium** same problem, problems encountered with IonCube. * After installing the latest IonCube successful, white screen error. * **Infomartion server.** * **PHP 5.6.26** (cli) (built: Sep 15 2016 14:57:05) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies with the **ionCube PHP Loader (enabled)** + Intrusion Protection from ioncube24.com( unconfigured) **v6.0.4**, Copyright (c) 2002-2016, by ionCube Ltd. with **Zend OPcache v7.0.6-dev**, Copyright (c) 1999-2016, by Zend Technologies Viewing 2 replies - 1 through 2 (of 2 total) The topic ‘Plugin Causing Fatal Error on Website.
