I had BulletProof Security version .47.1 installed and I attempted to update to .47.3. WordPress claimed the update was successful, and on the next page I received the following alerts:
"BPS Automatic htaccess File Update in Progress. Refresh Your Browser To Clear The BPS Alert.
BPS .47.1 Upgrade Notice
Adding new htaccess security filters included in version .47.2. Refresh your Browser to continue adding new security filters for version .47.3.
BPS Alert! A valid BPS htaccess file was NOT found in your wp-admin folder
If you are upgrading BPS this Alert will go away after you Refresh your Browser.
If you still see this Alert after refreshing your Browser then Activate BulletProof Mode for your wp-admin folder.
BulletProof Mode for the wp-admin folder MUST be activated when you have BulletProof Mode activated for the Root folder.
Check the BPS Security Status page to view your BPS Security Status."
The first time this happened I hit refresh on my browser and received 500 errors on my site and my site backend. Disabling/deleting the BPS plugin folder didn't correct. Through SFTP I restored the BPS plugin folder, root htaccess, and wp-admin htaccess from a backup I had (version .47.1.) The site then functioned correctly, but with the older version. I decided to try again and proceeded as above, but when the alerts appeared I clicked the link for the BPS Security Status page within the alert. The same 500 errors and corrections were made. I would love to update to the latest version but I am not sure what is interfering. Thanks in advance for your help.
