I checked my error log (created by nginx) for the last week and discovered that Better WP Security has generated a lot of errors when trying to create new records in bwps_log table. The error is below:
PHP message: WordPress database error Data too long for column 'referrer'
Looking at the data for referrer, they are URLs coming from Google which look quite long indeed.
Is that because the max no of characters in referrer column cant keep up with long URLs ? If yes, please suggest any solution.
