Today I upgraded from php 5.x to php 7.3 and removed php 5.x
completly. Now I found I get a blank screen calling roundcube.
I then added error_reporting(E_ALL); ini_set('display_errors',
'On');
and get Notice: Undefined index: env in
/usr/share/roundcubemail/index.php on line 46 Notice: Undefined
variable: rcmail_config in
/usr/share/roundcubemail/program/lib/Roundcube/rcube_config.php on
line 325 Notice: Undefined offset: 2 in
/usr/share/roundcubemail/program/lib/Roundcube/rcube_charset.php on
line 223
Is there a way to fix this? Should I install roundcube form
scratch?
you probably did something else than just replace the PHP binaries
we are currently on PHP 7.2 because 7.3 is far from production ready
when trivial code like below recently was broken no matter that we
have proper autotests for a 250000 LOC codebase which runs perfectly
with 7.3 and 7.4 HEAD
so i would not be suprised that you hit a similar or this bug
/** https://bugs.php.net/bug.php?id=78271 */
function bug78271($a, $b)
{
 if($a==10)
 {
  $w = "x";
 }
 else
 {
  $w = "y";
 }
 if($b)
 {
  $d1 = "none";
  $d2 = "block";
 }
 else
 {
  $d1 = "block";
  $d2 = "none";
 }
 return $d2.$b;
}
if(bug78271(1, 1) !== 'block1')
{
 trigger_error('https://bugs.php.net/bug.php?id=78271');
 $exit_code = 1;
}
why don't you learn to build packages for roundcube and PHP combined
with proper backups of your document roots so that you can upgrade and
downgrade and reinstall everything in a clean way?
But wait, on one server with CentOS 7 on which roundcube runs fine I have
$ php -v
PHP 7.3.7 (cli) (built: Jul  3 2019 11:30:22) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.7, Copyright (c) 1998-2018 Zend Technologies
    with the ionCube PHP Loader + ionCube24 v10.3.7, Copyright (c) 2002-2019, by ionCube Ltd.
    with Zend OPcache v7.3.7, Copyright (c) 1999-2018, by Zend Technologies
and on the server (I installed php 7.3 today) I get a blank screen
# php -v
PHP 7.3.7 (cli) (built: Jul  3 2019 11:30:22) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.7, Copyright (c) 1998-2018 Zend Technologies
I also changed <IfModule mod_php5.c> to <IfModule mod_php7.c> in the .htaccess
of roundcube but that did not change anything.
