If not, is probable that some type of malware scanning software is removing this file or preventing to add it * Also, our demo site is updated with the latest release without issue: [https://demo.gamipress.com/](https://demo.gamipress.com/) * Best regards * Thread Starter [Dountill](https://wordpress.org/support/users/dountill/) * (@dountill) * [5 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-in-latest-version-4/#post-13115589) * The file is there. Maybe you can see something in my whole error I got (redownloaded the plugin) * `Fatal error: Uncaught LogicException: Function 'rnl_autoloader' not found (function' rnl_autoloader' not found or invalid function name) in C:\Bitnami\wampstack-7.1.25- 0\apache2\htdocs\membertheme\wp-content\plugins\GamiPress-master\libraries\cmb2- metatabs-options\cmb2_metatabs_options.php:15 Stack trace: #0 C:\Bitnami\wampstack- 7.1.25-0\apache2\htdocs\membertheme\wp-content\plugins\GamiPress-master\libraries\ cmb2-metatabs-options\cmb2_metatabs_options.php(15): spl_autoload_register('rnl_autoloader')# 1 C:\Bitnami\wampstack-7.1.25-0\apache2\htdocs\membertheme\wp-content\plugins\ GamiPress-master\gamipress.php(168): require_once('C:\\Bitnami\\wamp...') #2 C:\Bitnami\wampstack-7.1.25-0\apache2\htdocs\membertheme\wp-content\plugins\GamiPress- master\gamipress.php(117): GamiPress->libraries() #3 C:\Bitnami\wampstack-7.1.25- 0\apache2\htdocs\membertheme\wp-content\plugins\GamiPress-master\gamipress.php( 406): GamiPress::instance() #4 C:\Bitnami\wampstack-7.1.25-0\apache2\htdocs\membertheme\ wp-content\plugins\GamiPress-master\gamip in C:\Bitnami\wampstack-7.1.25-0\apache2\ htdocs\membertheme\wp-content\plugins\GamiPress-master\libraries\cmb2-metatabs- options\cmb2_metatabs_options.php on line 15` * Thread Starter [Dountill](https://wordpress.org/support/users/dountill/) * (@dountill) * [5 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-in-latest-version-4/#post-13115632) * Seems that it is working on my live environment, but not on the development environment( windows) as shown above. * Plugin Author [Ruben Garcia](https://wordpress.org/support/users/rubengc/) * (@rubengc) * [5 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-in-latest-version-4/#post-13117285) * Hi [@dountill](https://wordpress.org/support/users/dountill/) * Then is really probable that the file gets blocked to be loaded on your local machine * Anyway, as I can see you are using the GitHub version, you could remove it and use the wordpress.org version instead but if the issue persist, look to exclude you xampp folder from any malware scanning software * best regards * Thread Starter [Dountill](https://wordpress.org/support/users/dountill/) * (@dountill) * [5 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-in-latest-version-4/#post-13120096) * As you can read in my first reply I tried both versions. WordPress repo and a GitHub build. Both with the same result. I checked the contents and everything is met, just like int the plug-in source. * Could it be the way the relative path is configured cannot be executed in a windows environment? * My virusscanner didn’t block any content or files in the plug-in. * Plugin Author [Ruben Garcia](https://wordpress.org/support/users/rubengc/) * (@rubengc) * [5 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-in-latest-version-4/#post-13120911) * Hi [@dountill](https://wordpress.org/support/users/dountill/) * Is probably that your Windows or xampp has some kind of different setup * I’m using windows to without issue * Could you try to edit the line 14 of the file `gamipress/libraries/cmb2-metatabs- options/cmb2_metatabs_options.php` and change this part `require 'autoloader. php';` by this one `require plugin_dir_path( __FILE__ ) . 'autoloader.php';` * Hope it helps * Thread Starter [Dountill](https://wordpress.org/support/users/dountill/) * (@dountill) * [5 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-in-latest-version-4/#post-13121383) * This indeed seems to help!
