Hi gcassandra,
Thank you for using Prime Mover plugin! First – please check with your host documentation/support on the correct way of adding custom wp-config.php constants. Some hosts will only allow adding these lines to their own hosting control panel. (e.g. RaidBoxes host)
Some custom server setups like Bedrock does not allow adding these directly to wp-config.php file but they their own config directory with configuration files where you can add the constants.
Also, please double check if you have added to the correct wp-config file path. Your server might have different WordPress sites installed (so many config files). Make sure the constant is added to actual wp-config.php path.
In addition, if your site uses OPcache – please clear it because it’s possible that the OpCache hasn’t pickup the changes you added to the wp-config.php. Once the opCache is cleared – try re-activating the plugin again. You can use this plugin to clear OPcache easily in WordPress.
Please refer to the following tutorials below on handling non-writable wp-config.php:
Once you have followed all the above suggestions, refresh the plugin page and try re-activating Prime Mover latest version (1.6.6). If you still see an error – please add the screenshot and send it to our official contact page since this contains sensitive information.
If the issue is resolved after following the above suggestions – please mark this ticket as resolved. Thanks again!
Thanks for the suggestions
Best regards
