Hello!

I've had urls switched to seo friendly for a long time, but yesterday when I updated the filters, it stopped working and gives me this error, when I turn off the seo friendly url from settings, it works perfectly, I'm using permalink manager pro, could the issue be with that two? sadly I can't deactivate the plugin since it's not working as the usual other plugins,

example url: https://prettyflowers.shop/en/flowers/swoof/style-birthday/

this is the error given :

 

Uncaught Error: html_entity_decode(): Argument #1 ($string) must be of type string, false given
in /home/prettyflowers/htdocs/prettyflowers.shop/wp-content/plugins/woocommerce/src/Blocks/BlockTypes/ProductFilters.php on line 276

Call stack:

  1. html_entity_decode()
    wp-content/plugins/woocommerce/src/Blocks/BlockTypes/ProductFilters.php:276
  2. Automattic\WooCommerce\Blocks\BlockTypes\ProductFilters::get_canonical_url_no_pagination()

Hello

The error you are seeing is not caused by HUSKY itself. It comes from WooCommerce's own ProductFilters block, which fails to parse the canonical URL when Permalink Manager Pro is active and SEO-friendly URLs are enabled.

The call stack shows the crash is in WooCommerce's ProductFilters.php at line 276, where it receives a false value instead of a string. This happens because your custom permalink structure from Permalink Manager Pro produces URLs like /en/flowers/swoof/style-birthday/ that WooCommerce's block cannot parse correctly.

Please try the following steps:

  1. Go to WooCommerce > Settings and check if you are using the native WooCommerce product filter block or the HUSKY filter widgets. If you have the WooCommerce Blocks-based filter active alongside HUSKY, try disabling the WooCommerce native filter block.
  2. Check if Permalink Manager Pro has a compatibility mode or a setting for WooCommerce — some versions have a dedicated WooCommerce integration tab.
  3. Try flushing permalinks: go to Settings > Permalinks and just click Save Changes without changing anything.
  4. Please also let us know your current versions of HUSKY, WooCommerce, and Permalink Manager Pro so we can investigate further.
