Hello @manuamaro – sorry for this inconvenience.
Could you send us a screenshot of the exact issue that you are having from your end?
In addition, I would suggest you check out this?documentation and see if it gives you anything useful to go on: Checking JavaScript Errors – https://docs.wppopupmaker.com/article/373-checking-javascript-errors
If that does not help, then may I ask, do you have any WooCommerce plugin active on your website? If yes, please be advised that after the latest update, there seems to be an issue and it is not our plugin but in a library, we share with several other prominent plugins like WooCommerce. Something is causing that libraries’ database tables not to generate in a small fraction of sites.
For more information, read this insight from our lead developer: https://www.ads-software.com/support/topic/critical-error-after-update-4/#post-13124120
Now, please try installing the Action Scheduler plugin as a workaround fix.
Some users had luck fixing it by installing the plugin directly:?https://github.com/woocommerce/action-scheduler/releases
I hope that helps.
