I installed a plugin that was working on my old wordpress website, but now its throwing fatal error wordpress version is 6.3.
Fatal error: Uncaught Error: Class “AmiutProductSpecsApp” not found in /home/mobilopk/public_html/wp-content/plugins/product-specifications-main/wc-specs.php:34 Stack trace: #0 /home/mobilopk/public_html/wp-content/plugins/product-specifications-main/wc-specs.php(38): dwspecs_table() #1 /home/mobilopk/public_html/wp-admin/includes/plugin.php(2318): include_once(‘/home/mobilopk/…’) #2 /home/mobilopk/public_html/wp-admin/plugins.php(192): plugin_sandbox_scrape() #3 {main} thrown in /home/mobilopk/public_html/wp-content/plugins/product-specifications-main/wc-specs.php on line 34
