Hi,
sorry for the delay on my response here!
Please, try to activate the “Save in background” option, in order to allow the system to save in little chunks in more processes: https://snipboard.io/kFDe4L.jpg
This is important with shops with many products, such as your case.
If it doesn’t work yet, please try to reduce the number of products saved in one each process. To do that, the only way, unfortunately now, is changing it in the plugin code, though it will be useful to me to understand if it solves the problem and then I’ll give a way to change it.
Open the plugin file wp-content/plugins/pixel-caffeine/includes/product-catalogs/class-configuration-defaults.php and find the line:
Configuration::OPTION_CHUNK_LIMIT => 1000
Change that 1000 to something less, such 500 or less, until the error goes away.
I’m working on a new version that will be available early next week. In that version you will be able to change this parameter without touching the code, but at the moment you can fix immediately by changing the code. If you will upgrade, remember to change the value in the new parameter as well.
Let me know if you can solve that in this way.
