How do we remove the MPN from the product pages?

Thanks for sharing the screenshots. Unfortunately, I cannot view the “Product Identifiers” one. It shows just a white screen. Can you please check?

The last two tabs do not load, they just show blank pages. I already mentioned this to you in this post…?

It says the plugin uses too much memory for the page to render. Every other settings page of the plugin loads correctly.

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 73728 bytes) in /wp-includes/functions.php on line 4755

Do you get this error even when all other plugins are disabled using ‘Health Check & Troubleshooting’ plugin?

If this is the case, then the ‘postmeta’ table on your site is just too big and the web server cannot fetch all the product attributes using the available memory.

Please consider deleting unused meta fields from the ‘postmeta’ table or allocating additional memory.

Hi,

I already replied 1 week ago. When your plugin is the only plugin running, you receive this error:

Error Details
=============
An error of type E_ERROR was caused in line 292 of the file /wp-content/plugins/customer-reviews-woocommerce/class-cr-product-feed-identifiers.php. Error message: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes)

I ran an orphan row search on the postmeta table and there are no blank rows.

Well, then it definitely looks like you have a lot of product meta fields in the ‘postmeta’ table. Your web server cannot fetch all the product attributes using the available memory.

Please consider deleting unused meta fields from the ‘postmeta’ table or allocating additional memory.

I ran an orphan row search on the postmeta table and there are no blank rows.

Blank rows wouldn’t cause this memory issue because the plugin would skip them. The problem is due to non-blank rows. Your web server runs out of memory when trying to fetch non-blank rows to display available product attributes.

Here is a screenshot of how your plugin looks in troubleshooting mode.

There is no ‘SAVE CHANGES’ button in order to save the changes to remove all of the data from product pages. There is a ‘SAVE CHANGES’ button on all 3 of the other tabs.

We can only see that page in troubleshooting mode as the plugin cannot handle loading it without troubleshooting mode.

Thanks for providing additional information.

Can you please confirm if you also receive an email from WordPress about the memory error when opening the tab from this screenshot: https://pasteboard.co/JIT3ea7.png ?

WordPress version 5.6
Current plugin: Customer Reviews for WooCommerce (version 3.140)
PHP version 7.4.13

I’m sorry. Is it the answer to my last question? Can you please confirm if you also receive an email from WordPress about the memory error when opening the tab from this screenshot: https://pasteboard.co/JIT3ea7.png ?

Hi, we already sent this 3 weeks, 2 days ago, in this same thread.

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Customer Reviews for WooCommerce.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.6
Current theme: Universal Store (version 1.0.5)
Current plugin: Customer Reviews for WooCommerce (version 3.140)
PHP version 7.4.13

Just enabled troubleshooting mode again for you.

Upon clicking the “Product Identifiers” link, you get the below email. You also do not see ANY button to save the settings on that page. The save button exists only on every other page, per the screenshot we sent earlier in this thread. So we cannot save the settings in troubleshooting mode.

First, visit your website and check for any visible issues. Next, visit the page where the error was caught (/wp-admin/admin.php?page=ivole-reviews-product-feed&tab=identifiers) and check for any visible issues.

Thanks for providing additional information!

You do not see the save button because the web server runs out of memory while fetching the product attributes from the ‘postmeta’ table. It happens before the server gets a chance to render the Save button.

Please consider decreasing size of the ‘postmeta’ table or allocating additional memory.

We haven’t heard from you for more than two weeks. For this reason, I’ll assume that either you are not interested in this question/problem anymore or it has been resolved. If this is not the case, please let us know and we’ll be happy to help.
