Hello. Suddenly i get lot of this error in error_log : Code: 2018-04-05 08:32:47.370472 [NOTICE] [x.x.x.x:28043] [STDERR] PHP Fatal error: Unknown: Failed opening required '/home/*****/public_html/*****.php' (include_path='.:/opt/cpanel/ea-php71/root/usr/share/pear') in Unknown on line 0 And looking at the cpanel account name, it happens only on accounts which use PHP 7.1. On accounts which use PHP 7.0, there are no error messages. This just happened since yesterday (because i noticed i experienced lot of HTTP 500 errors, so i started to check the log). According to PHP 7.1 changelog, PHP 7.1.6 which i have at this moment was released 29 March (about 1 week ago). So i am not sure if it is caused by latest PHP 7.1 incremental update or not. If i changed the PHP on those accounts from PHP 7.1 to 7.0, there are no more error messages. But when i switched back to 7.1, error messages are starting to appear again. I have compared PHP.ini between 7.0 & 7.1, there is no difference. Do you have any idea what should i check? Thank you.
