A PHP|php.ini Handler was Not found in your Root .htaccess file – should probably be changed to: A PHP|php.ini Handler .htacess code was Not found in your Root .htaccess file. That check is looking in your root .htaccess file for that code. The PHP File Finder looks for php.ini files.
I have seen around 5 individual cases total in 14 months of this particular php error. The general theme for the cause/source of the the error is something outside of BPS is causing a problem for BPS, which then generates that php error. There seems to be a range of things that can break this BPS function so what I will be looking at is changing the BPS Pro function itself – ie be resistant/resilient against whatever is breaking this particular function.
