Invoice date 01.01.1970

Hi @openstream,

Thanks for reaching out.

The cause of this issue is usually due to the installed Firewall on your website. WordFence and Sucuri are identified as common firewalls causing issues. The firewall may be blocking the action used for saving the plugin settings. The common workaround that we would suggest would be to whitelist the action that is blocking the settings from saving. Note that the user with admin provisions will only have access to whitelist the action. Check it in that way and let us know how it goes.

If the issue persists, please get back to us by sharing the WooCommerce system status report (WooCommerce>status>system status report) and the error page screenshot for a better understanding.

Thanks for your reply, we’re not using a security plugin. I just disabled the Litespeed caching plugin, but I still cannot save the template. I’m gonna install the site locally to see if it behaves the same and ask the hosting provider if they’re using any firewalls.

But the real problem is actually that the date always shows as January 1, 1970. Here’s the WooCommerce system report. Here are 2 screenshots from the PDF invoice and the order itself in WooCommerce

Hi @openstream,

Thanks for sharing the information. We couldn’t replicate the issue when we tested the scenario on our end. Please make sure that you are not using any custom codes on your site that could be affecting the dates. To assist with further investigation, we kindly ask that you share your active theme’s functions.php via this link.

Hi @openstream

We have fixed the issue in version 4.1.0.1. Please update the plugin to resolve the issue.

We were able to fix this in the meantime.

We disabled/re-enabled the plugin to generate missing tables/columns. Also in our functions.php were 3 functions that manipulate the date format from an older plugin version.
