Most likely this is caused by a plugin conflict, so I would advise you to perform a full conflict test to rule out eventual issues with the theme or a different plugin. We recommend temporarily activating the [default theme Storefront](https://wordpress.org/themes/storefront/) and disabling all other plugins except for WooCommerce and PayPal Payments to see if the behaviour persists. * Here’s a guide that explains the steps in more detail: [How to test for conflicts](https://woocommerce.com/document/how-to-test-for-conflicts/). * If this does not identify what is causing this, you can always still [open a private engagement with us](https://zettle.inpsyde.com/docs/request-support/), and share the logs with us for us to have a look at and see what else we can do. * Kind regards, Joost * Thread Starter [Mati](https://wordpress.org/support/users/mattheus/) * (@mattheus) * [2 years, 4 months ago](https://wordpress.org/support/topic/zettle-plugin-when-activated-causing-wordpress-critical-error-2/#post-17343771) * Thanks for your comment. While I was creating this ticket, I contacted Zettle support by telephone. During telephone support we discovered that it was due to the plugin “Docket Cache”. so that problem solved. * next problems. **Problem 1**Together with zettle support, I reconnected to the shop and zettle account perhaps 5 times. The reason is that products are not synchronized. There is also no reason given why it is not Syncable. [check image](https://prnt.sc/ebm0tfmF5wNQ) The Zettle employee also thought this was strange. It does indicate errors in the log file. * **Porblem 2** There are also products that are not synthesized for a reason, for example “Unsupported product type”. I understand this reason. I just can’t figure out the products without a reason. . [check image](https://prnt.sc/3EAsXBC556Yb) is it also possible to publish bundled products in zettle? - This reply was modified 2 years, 4 months ago by [Mati](https://wordpress.org/support/users/mattheus/). - This reply was modified 2 years, 4 months ago by [Mati](https://wordpress.org/support/users/mattheus/). * Plugin Support [Syde Joost](https://wordpress.org/support/users/joostvandevijver/) * (@joostvandevijver) * [2 years, 4 months ago](https://wordpress.org/support/topic/zettle-plugin-when-activated-causing-wordpress-critical-error-2/#post-17343947) * Hello [@mattheus](https://wordpress.org/support/users/mattheus/), * On the 2nd question, I can give you a clear answer: no, in the current state of our plugin, you cannot sync bundled products to Zettle. Only the products mentioned in our documentation can be synced at this time. * The cause for this last product to not sync and not show any error (in the status or logs) is a strange one. If I was looking into this, I would start by checking if the tax settings / tax class would be correctly assigned and configured. The most common cause is that a tax class is assigned to a product, but that this product does not have any entry of the tax configuration in this tax class. That could cause this situation. * If this is not the case, we could have a closer look, but it might be best to [open a private engagement with u](https://zettle.inpsyde.com/docs/request-support/) s, in order to not share details on a public forum. * Kind regards, Joost * Thread Starter [Mati](https://wordpress.org/support/users/mattheus/) * (@mattheus) * [2 years, 4 months ago](https://wordpress.org/support/topic/zettle-plugin-when-activated-causing-wordpress-critical-error-2/#post-17344414) * clearly for the bundles, that’s where it ends. * For the products that are not synced, I first checked the tax settings, etc., also together with your colleague by telephone. In the toilet log file it does indicate something * I see that WC logs have different log dates, maybe take a look? Otherwise, why not create a private ticket? Then we can also talk in Dutch, which is a bit easier ​ * # Previous: Inpsyde\Zettle\PhpSdk\Exception\Validator\Image\ImageNotFoundException: No Attachment found for Attachment ID: 10125 in /customers/2/0/c/musclemachinenutrition. nl/httpd.www/wp-content/plugins/zettle-pos-integration/modules/zettle-php-sdk/ src/Validator/WordPressImageValidator.php:99 2024-01-12T16:51:31+00:00 INFO Inpsyde\ Zettle\PhpSdk\Exception\InvalidBuilderPayloadException: Could not build Inpsyde\ Zettle\PhpSdk\DAL\Entity\Presentation\Presentation from the given payload in / customers/2/0/c/musclemachinenutrition.nl/httpd.www/wp-content/plugins/zettle- pos-integration/modules/zettle-php-sdk/src/Builder/ValidatableBuilder.php:52 # Previous: Inpsyde\Zettle\PhpSdk\Exception\InvalidBuilderPayloadException: Could not build Inpsyde\Zettle\PhpSdk\DAL\Entity\Image\ImageInterface from the given payload in /customers/2/0/c/musclemachinenutrition.nl/httpd.www/wp-content/plugins/ zettle-pos-integration/modules/zettle-php-sdk/src/Builder/ValidatableBuilder. php:52 # Previous: Inpsyde\Zettle\PhpSdk\Exception\Validator\Image\ImageNotFoundException: No Attachment found for Attachment ID: 10125 in /customers/2/0/c/musclemachinenutrition. nl/httpd.www/wp-content/plugins/zettle-pos-integration/modules/zettle-php-sdk/ src/Validator/WordPressImageValidator.php:99 2024-01-12T16:51:31+00:00 WARNING Skipping WC_Product_Variable 789, not syncable because: Excluded. 2024-01-12T16: 51:31+00:00 DEBUG Executed Job ‘sync-product’ with ID 28. 2024-01-12T16:51:31 +00:00 DEBUG Removed 1 jobs from the queue 2024-01-12T16:51:31+00:00 INFO Remote UUID of product with ID 789 not found 2024-01-12T16:51:31+00:00 DEBUG Executed Job ‘delete-product’ with ID 29. 2024-01-12T16:51:31+00:00 DEBUG Removed 1 jobs from the queue 2024-01-12T16:51:31+00:00 WARNING No remote ID found for local ID 789 2024-01-12T16:51:31+00:00 DEBUG Executed Job ‘unlink-product’ with ID 30. 2024-01-12T16:51:31+00:00 DEBUG Removed 1 jobs from the queue 2024-01-12T16: 51:31+00:00 DEBUG Added 1 jobs to the queue 2024-01-12T16:51:31+00:00 NOTICE Job ‘unlink-product’ with ID 30 failed 1/3 times and will run again 2024-01-12T16: 51:31+00:00 WARNING No remote ID found for local ID 789 2024-01-12T16:51:31+00: 00 DEBUG Executed Job ‘unlink-product’ with ID 31. 2024-01-12T16:51:31+00:00 DEBUG Removed 1 jobs from the queue 2024-01-12T16:51:31+00:00 DEBUG Added 1 jobs to the queue 2024-01-12T16:51:31+00:00 NOTICE Job ‘unlink-product’ with ID 31 failed 2/3 times and will run again 2024-01-12T16:51:31+00:00 WARNING No remote ID found for local ID 789 2024-01-12T16:51:31+00:00 DEBUG Executed Job ‘unlink- product’ with ID 32. 2024-01-12T16:51:31+00:00 DEBUG Removed 1 jobs from the queue 2024-01-12T16:51:31+00:00 DEBUG Added 1 jobs to the queue 2024-01-12T16: 51:31+00:00 NOTICE Job ‘unlink-product’ with ID 32 failed 3/3 times and will run again 2024-01-12T16:51:31+00:00 WARNING No remote ID found for local ID 789 2024-01-12T16:51:31+00:00 DEBUG Executed Job ‘unlink-product’ with ID 33. 2024- 01-12T16:51:31+00:00 DEBUG Removed 1 jobs from the queue 2024-01-12T16:51:31+ 00:00 NOTICE Job ‘unlink-product’ with ID 33 has failed 3 times and will NOT run again 2024-01-12T16:51:34+00:00 INFO Inpsyde\Zettle\PhpSdk\Exception\InvalidBuilderPayloadException: Could not build Inpsyde\Zettle\PhpSdk\DAL\Entity\Presentation\Presentation from the given payload in /customers/2/0/c/musclemachinenutrition.nl/httpd.www/wp- content/plugins/zettle-pos-integration/modules/zettle-php-sdk/src/Builder/ValidatableBuilder. php:52 * Plugin Support [Syde Joost](https://wordpress.org/support/users/joostvandevijver/) * (@joostvandevijver) * [2 years, 4 months ago](https://wordpress.org/support/topic/zettle-plugin-when-activated-causing-wordpress-critical-error-2/#post-17344497) * Hello [@mattheus](https://wordpress.org/support/users/mattheus/), * these logs seem to be related to image sync failures and those should not affect the product sync; it should only exclude the image from syncing. * Before opening that private engagement, maybe you should create a new product with the same specs as the one that is not synchronizing and see if that syncs to Zettle?
