Encountering the error message "Plugin could not be activated because it triggered a fatal error" can be frustrating, but there are several steps you can take to troubleshoot and resolve the issue. Follow these instructions to address the problem:
Method 1: Disable the Free Version and Activate the PRO Version
If you have both the Free and PRO versions of the plugin installed, try deactivating the Free version before activating the PRO version.
Navigate to the Plugins section in your WordPress dashboard.
Find the Free version of the plugin and deactivate it.
Attempt to activate the PRO version again.
Method 2: Keep the License When Disabling
When prompted by the plugin if you want to disable the license, choose to keep the license intact.
This ensures that your license remains valid and can be used when reactivating the plugin.
Method 3: Re-download and Upload the PRO Version
If the error persists, download the PRO version of the plugin again from the source.
Ensure that the downloaded file is in ZIP format.
Try uploading the plugin ZIP file again through the WordPress dashboard.
Additional Tips:
Ensure that the PRO version of the plugin is compatible with your WordPress version.
Check if any conflicting plugins or themes are causing the issue by deactivating them temporarily.
