Fatal error upon activating plugin

Hi I just now decided to test out your plugin and after activating received this message: Fatal error: Uncaught Error: Class 'iFolders\App' not found in /home/easywebd/dev.easywebdesigntutorials.com/wp-content/plugins/ifolders/ifolders.php:99 Stack trace: #0 /home/easywebd/dev.easywebdesigntutorials.com/wp-includes/class-wp-hook.php(307): iFolders\Plugin::loaded('') #1 /home/easywebd/dev.easywebdesigntutorials.com/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #2 /home/easywebd/dev.easywebdesigntutorials.com/wp-includes/plugin.php(476): WP_Hook->do_action(Array) #3 /home/easywebd/dev.easywebdesigntutorials.com/wp-settings.php(461): do_action('plugins_loaded') #4 /home/easywebd/dev.easywebdesigntutorials.com/wp-config.php(90): require_once('/home/easywebd/...') #5 /home/easywebd/dev.easywebdesigntutorials.com/wp-load.php(50): require_once('/home/easywebd/...') #6 /home/easywebd/dev.easywebdesigntutorials.com/wp-admin/admin.php(34): require_once('/home/easywebd/...') #7 /home/easywebd/dev.easywebdesigntutorials.com/wp-admin/plugins.php(10): require_once('/home/easywebd/...') #8 {main} in /home/easywebd/dev.easywebdesigntutorials.com/wp-content/plugins/ifolders/ifolders.php on line 99 Hello. What PHP version do you use? And WP? This reply was modified 3 years, 10 months ago by Avirtum . Hi This is a dev site running WordPress version 6.0.2. PHP version 7.4 Blocksy theme. Various plugins are in use. Security: All in One WP Security Breeze Code Snippets etc I installed and activated the plugin again. Fatal error came back. Query Monitor is active. I noticed your e-mail and will send you a temporary access link. This reply was modified 3 years, 10 months ago by Paal Joachim Romdahl . Thanks. I saw your email. I will try to reproduce this error in my env and report the results. This will take some time. I think I have found the problem. The Linux is case sensitive with filenames, but my Win OS not. As result the php autoloader works incorectly. That’s why I just didn’t see it in my dev env. I will fix this and report back soon. This reply was modified 3 years, 10 months ago by Avirtum . I have fixed it in v1.0.1. As I said above, it was about case sensitive with filenames. Thank you for the fix!
