Error while saving products

It sounds like the server is timing out before it finishes saving the batch. Instead of saving all records at the same time, we batch them into 25 so that servers can finish processing them before moving on to the next batch.

On some hosts, 25 is still too high and the batches need to be smaller so they can complete successfully before the web browser gives up and stops waiting (throwing an error).

To adjust the batch size perform the following steps:

1. Log into your FTP site and edit wp-config.php
2. Edit wp-config.php and scroll to the end and add the following bit of code:

Scroll towards the bottom, and before the line that says “Happy blogging.” add this code ABOVE that line (translate as needed):

define( 'PWBE_SAVE_BATCH_SIZE', 5 );

/* That's all, stop editing! Happy blogging. */

3. Save the wp-config.php file and re-upload it to your server.

Adjust the value until you find the sweet spot where it doesn’t timeout. A batch size of 1 will save each field one after the other.

If you have any questions just let me know!

Check the PHP error log and see if there are any clues as to what is stopping the process from saving.

Perform the following steps please:

1. Log into your FTP site and edit wp-config.php
2. Set the following values (add the lines if they don’t exist):

    define( 'WP_DEBUG', true );
    define( 'WP_DEBUG_LOG', true );
    define( 'WP_DEBUG_DISPLAY', false );
    @ini_set( 'display_errors', 0 );

3. Return to the site and trigger the error again by trying to save.
4. Now go back to FTP and look at the file /wp-content/debug.log
5. Return to wp-config.php and set DEBUG back to false (reverting the changes made in Step 2)

Let me know if you have any questions!

Thanks for following up, glad to hear you got it sorted out. Best of luck with your store!
