Of course! First of all, please download the plugin again, there was a bug that caused the “31 characters” error, it is fixed by now.
To make sure, that the plugin will 100% work, please proceed with the following steps:
1. delete the plugin with the wordpress plugin manager
2. Check if the search directory indeed got deleted by checking the wp-content/plugins/ajax-search-pro directory. If it still exists, delete it.
3. Open up the PHPMyadmin or any mysql tool you use and delete the wp_ajaxsearchpro and wp_ajaxsearchpro_statistics tables if they are present.
4. Install the new version from codecanyon.
After these steps you shouldn't experience any errors, it produces a clean install.Best,
