Changes don’t save

Normally when saving the changes there is a “Your settings have been saved.” message, as in this screenshot. Do you get such a message?

What WordPress and PHP versions do you have? Are there any PHP errors in the debug.log file?

I don’t see a screenshot in your message, but no, I get no message of “Your settings have been saved” I get no message at all. Upon clicking save changes the page reloads, with the default settings selected again.

PHP Version: 7.3.11
WordPress: 5.3.2

There are a couple of php notices in the debug log related to a different plugin [11-Feb-2020 15:32:23 UTC] PHP Notice: Undefined index: tag in public_html/wp-content/plugins/oxygen/component-framework/includes/cache.php on line 697

I also decided to try a fresh install on another website, and the same issue occurs. This second site has no errors in the debug log.

The php version for this second site is 7.2.24 & WordPress version is also 5.3.2

I tried in both up to date versions of firefox and chrome, and also disabled ad-blocker in case that was an issue.

One thing I noticed between the two installs, is that even though i deleted and reinstalled on the first site, it has absolutely no checkboxes filled out on the ‘general settings’ tab (it seems like it remembered my de-selections from before the update), whereas a fresh install on the second site, where it’s never been installed, has 3 checkboxes filled out.

Would you please update the plugin to the 1.39.1 version and check if you can save the settings?

Wow, you work so fast! Thank you so much, everything works as normal on both sites now, and I get the save message again.

Thank you for your detailed report. That was very helpful ??
