Fatal error

Hi, everything was working fine on the page, I tried to make a test purchase to make sure evething was working alright but when going to the checkout it showed this error:

Fatal error: Uncaught Error: Class “WC_Legacy_API” not found in /home/grupopsi/public_html/wp-content/plugins/woocommerce/includes/class-wc-api.php:19 Stack trace: #0 /home/grupopsi/public_html/wp-content/plugins/woocommerce/includes/class-wc-autoloader.php(54): include_once() #1 /home/grupopsi/public_html/wp-content/plugins/woocommerce/includes/class-wc-autoloader.php(98): WC_Autoloader->load_file(‘/home/grupopsi/…’) #2 [internal function]: WC_Autoloader->autoload(‘wc_api’) #3 /home/grupopsi/public_html/wp-content/plugins/woocommerce/src/Internal/Utilities/LegacyRestApiStub.php(61): class_exists(‘WC_API’) #4 [internal function]: Automattic\WooCommerce\Internal\Utilities\LegacyRestApiStub::parse_legacy_rest_api_request(Object(WP)) #5 /home/grupopsi/public_html/wp-content/plugins/woocommerce/src/Internal/Traits/AccessiblePrivateMethods.php(178): call_user_func_array(Array, Array) #6 /home/grupopsi/public_html/wp-includes/class-wp-hook.php(324): Automattic\WooCommerce\Internal\Utilities\LegacyRestApiStub::__callStatic(‘parse_legacy_re…’, Array) #7 /home/grupopsi/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #8 /home/grupopsi/public_html/wp-includes/plugin.php(565): WP_Hook->do_action(Array) #9 /home/grupopsi/public_html/wp-includes/class-wp.php(418): do_action_ref_array(‘parse_request’, Array) #10 /home/grupopsi/public_html/wp-includes/class-wp.php(813): WP->parse_request(”) #11 /home/grupopsi/public_html/wp-includes/functions.php(1336): WP->main(”) #12 /home/grupopsi/public_html/wp-blog-header.php(16): wp() #13 /home/grupopsi/public_html/index.php(17): require(‘/home/grupopsi/…’) #14 {main} thrown in?/home/grupopsi/public_html/wp-content/plugins/woocommerce/includes/class-wc-api.php?on line?19

I’m Using blocksy as a theme, but I alredy tried with a different theme and desactivating all the plugins, all works with everything turned on, but WooCommmerce.

Thanks in advance for the help ??
