Hi Mariusz,
thank you very much for your answer.
I’m sorry but I don’t know what are transients and so I’ve installed the plugin Transient Manager to understand if I could enable all: can you explain how to enable all?
I’ve also post the question in WooCommerce forum, but one aswer was that I’ve to try to disable all the plugins and re-enable one by one to see which one is the responsible of the issue. I’m going slightly mad about this problem…
Thanks again,
M
