The pro pack name always should be “wp-sms-pro”, but it was released as “wp-sms-pro-v3.2”, which caused the pro pack’s features to be disabled on the settings page.
The following solutions should be used before updating to the new version, which also fixes the naming error:
1. Upgrade Manually
Please disable and then delete wp-sms-pro-v3.2 on your WordPress, then get the latest version from your account and install that.
2. Renaming the Plugin
You can also rename the current plugin name from wp-sms-pro-v3.2 to wp-sms-pro, then try to update the plugin to the new version without any problem.
