It did happen on the first save. Though it was ignored. Now, it has happened on a later save. So reported. * Plugin Author [alekv](https://wordpress.org/support/users/alekv/) * (@alekv) * [5 years, 1 month ago](https://wordpress.org/support/topic/critical-error-186/#post-14372972) * Can you remember what settings you changed before that save? * Thread Starter [bling007](https://wordpress.org/support/users/bling007/) * (@bling007) * [5 years, 1 month ago](https://wordpress.org/support/topic/critical-error-186/#post-14372978) * I was saving Google UA analytics id. The first time – I saved G4 id which threw the error I think. * Currently running both G4 and UA. * Plugin Author [alekv](https://wordpress.org/support/users/alekv/) * (@alekv) * [5 years, 1 month ago](https://wordpress.org/support/topic/critical-error-186/#post-14373011) * And you are running the free version and have never tried the pro version, correct? * Thread Starter [bling007](https://wordpress.org/support/users/bling007/) * (@bling007) * [5 years, 1 month ago](https://wordpress.org/support/topic/critical-error-186/#post-14373030) * Yes. Unless the plugin name has changed. I have been trying many plugins for years. This is a new trial. * Switched from: [https://wordpress.org/plugins/woocommerce-conversion-tracking/](https://wordpress.org/plugins/woocommerce-conversion-tracking/) Tried before: [https://wordpress.org/plugins/woocommerce-google-dynamic-retargeting-tag/](https://wordpress.org/plugins/woocommerce-google-dynamic-retargeting-tag/) * Also currently installed and running: [https://wordpress.org/plugins/woocommerce-google-analytics-integration/](https://wordpress.org/plugins/woocommerce-google-analytics-integration/) * Above does enhanced e-commerce tracking. * Plugin Author [alekv](https://wordpress.org/support/users/alekv/) * (@alekv) * [5 years, 1 month ago](https://wordpress.org/support/topic/critical-error-186/#post-14373357) * I think I found the issue. * Shortly after saving the new options, on the next immediate run the plugin would read the options from the cache instead from the new saved ones. This is why the error happens so rarely and only on saving new settings. * I’ll push an update soon that should fix this. * Thanks for reporting it and sharing all those details. * I’ll mark issue resolved, as it is not constantly happening and the new update should fix it. * If it happens again after the update (which it shouldn’t), please let me know. * Thread Starter [bling007](https://wordpress.org/support/users/bling007/) * (@bling007) * [5 years, 1 month ago](https://wordpress.org/support/topic/critical-error-186/#post-14373400) * Appreciate such prompt support.
