Hi thank you for your bug reporting, sorry for late response.
Currently, the plugin use wp_head hook to catch all loaded js and css files, once finished it generate the merged files (e.g merged-js-435654.js) and add it to wp_enqueue_script

Unfortunately, if there is no found assets, such as image, js, css files, WordPress will run 404 page in the background and run the plugin again in the background too, along with that, the plugin will create new merged files (e.g merged-js-909876.js) and delete the old one.

Because the plugin have added merged-js-435654.js to the wp_enqueue_script, and the merged files changed, so wordpress can’t find that file.

To solve this, there is an option in the setting page to not run the plugin on the 404 page, so if there are missing assets and wordpress run the 404 page in the background, the plugin stop to run.

Hi, thank you for your reply

The possible condition of the missing merged files occur is the 404 page run in the background, if you face the problem again, please check if there is not found assets.

Currently, deactivating and then activating the plugin doesn’t create the new merged files. There are two conditions when the plugin generates new merged files

• Merged files not found. By deleting that files, the plugin will generate new ones.

  Deleting the files can be done through plugin setting page. On that page, scroll down to the bottom and click Clear All Cache. once deleted the plugin will generate the new merged files.

• Found new css or js files. If there are new css or js files, the plugin will generate new merged files

In your situation, by changing the theme, the plugin detects new css and js files, then generate new merged files.

Btw, nice website 🙂
