Recently, we have observed that our awesome themes are occasionally reverting to their default settings, causing all customizations to be lost. This issue disrupts the user experience and undermines the reliability of our themes. Please help us with this issue.

We experience this too. We have a custom theme set and it gets switched off and reverts back to the default. We thought at first it was down to a user making a change but this is not the case.

We haven’t been able to pin down what triggers the custom theme to be disabled.

Hi Jacqueline and Jeremy,

Thank you both for reporting this. I was able to reproduce this obscure issue and identify the cause.

The theme settings page was processing form data unconditionally on every request, including empty or incomplete ones. When that happened, all checkbox-based settings (custom theme toggle, scroll-to-top, consent message, custom CSS, etc.) were being blanked out and saved over your actual configuration. This could be triggered by things like a server’s post_max_size being exceeded, a truncated request from a slow connection, or even a browser glitch, which explains why it seemed random and was so hard to pin down.

Apologies for the frustration this has caused. A fix will be included in the next release.
