HI Siprof,
Sorry didn’t mention the options in my previous response.
Those you mentioned are the tables where the WordPress security alerts are stored, hence by deleting those you are deleting all the alerts.
The plugin options are stored in the wp_options table in the WordPress database. Those related to pruning are mainly the following:
wsal-pruning-date
wsal-pruning-limit-e
wsal-pruning-limit
The next step is:
1. Disable the plugin
2. Access the WordPress database using phpMyAdmin or something similar
3. Browse through the wp_options table (wp_ is the default prefix, you might have changed it)
4. Find the below options:
wsal-pruning-date
wsal-pruning-limit-e
wsal-pruning-limit
5. Delete these options
6. Activate the plugin
7. Configure again the pruning options.
This should work.
Let me know how it goes or if you have any further queries.
