Version 3.8.6
-
Hello
I am not allowed to do any more update otherwise I have an error and the website can no longer be seen. Version 3.8.6 is the last one, followed by a critical bug. I found out that when I disable the plugin ‘Plugin Manager’, the web page comes back and it doesn’t show a critical error.Do you know what to do?
The page I need help with: [log in to see the link]

Hi @pacson
Sorry to hear that!
Would you be willing to try this beta version? If so, please add the following code snippet just before replacing the plugin:
add_filter( 'wpo_wcpdf_filesystem_method', function( $method ) {
return 'php';
} );Let us know your feedback!
Thank you.
I pasted the code into Snippet Code and installed the beta. I tried, but the critical error comes back.Could you please check under WooCommerce > Status > Logs to see if there are any related errors?
I don’t find any errors, just a warning, in plugin-woocommerce-2025-04-09
“Got blank templates from PTK Pattern Store”.However, if I go under Woo>> status under woocommerce pages at e.g. shopping cart: The page does not contain the [woocommerce_cart] shortcode or woocommerce/cart block. or under checkout: The page does not contain the [woocommerce_cart] shortcode or woocommerce/cart block.
They work with Divi single blocks.Otherwise there are no errors
Do you have WP debug enabled?
sorry no, im not good in website
Add this to your
wp-config.phpfile:// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );Try to reproduce the error, then check the
/wp-content/debug.logfile to see if any related errors have been logged.I tried, but the folder is not there debug.log
i try with chatgpt
ok, this is in debug
