Uninstalled and 500 error went away. Also see this error: * > 436 PHP Fatal error: Uncaught JSMin_UnterminatedStringException: JSMin: Unterminated > String at byte 281: ‘use strict\\’; in /nas/content/live/barebabystore/wp-content/ > plugins/autoptimize/classes/external/php/jsmin.php:214\nStack trace:\n#0 /nas/ > content/live/barebabystore/wp-content/plugins/autoptimize/classes/external/ > php/jsmin.php(152): JSMin->action(1)\n#1 /nas/content/live/barebabystore/wp- > content/plugins/autoptimize/classes/external/php/jsmin.php(86): JSMin->min()\ > n#2 /nas/content/live/barebabystore/wp-content/plugins/autoptimize/classes/ > autoptimizeSpeedupper.php(38): JSMin::minify(‘/*!\\r\\n * @copyri…’)\n#3 /nas/ > content/live/barebabystore/wp-includes/class-wp-hook.php(307): autoptimizeSpeedupper- > >js_snippetcacher(‘/*!\\r\\n * @copyri…’, ‘/nas/content/li…’)\n#4 /nas/content/ > live/barebabystore/wp-includes/plugin.php(189): WP_Hook->apply_filters(‘/*!\\ > r\\n * @copyri…’, Array)\n#5 /nas/content/live/barebabystore/wp-content/plugins/ > autoptimize/classes/autoptimizeScripts.php(554): apply_filters(‘autoptimize_js_…’,‘/*!\\ > r\\n * @copyri. in /nas/content/live/barebabystore/wp-content/plugins/autoptimize/ > classes/external/php/jsmin.php on line 214 * Any idea what might be going on?

If so, are you saying to enter them one at a time and check? * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-4100/#post-15447158) * indeed, goal is to narrow down things step by step 🙂 * Thread Starter [KentyMac](https://wordpress.org/support/users/kentymac/) * (@kentymac) * [4 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-4100/#post-15447330) * OK, I excluded wp-content/plugins and the fatal errors seem to have stopped.
