Hey there,
I understand you’re getting a PHP warning on your site with Solid Security Pro.
This has been reported in the past and was resolved once the user uninstalled and reinstalled Solid Security Pro on their website.
When you uninstall and delete Solid Security Pro from the WP Plugins page, it runs a cleanup script and removes itself from the site, including the database. Anything left over is temporary data (transients/cron jobs) that WordPress stores.
<span style=”box-sizing: border-box; margin: 0px; padding: 0px;”>Once deleted, please clear all caches in this manner:?server cache -> CDN cache (if you use it) -> plugin cache -> browser cache?before installing a fresh copy of the latest plugin version, which you can grab from your?SolidWP Member Panel.</span>
I recommend?backing up?your site before you make any changes.
Please let me know if uninstalling and re-installing Solid Security Pro helped or if you have other questions.
Best regards,
Kevin
