Hi community!


So, I'm running LimeSurvey CE on 3.14.x currently, updating to 3.15.x soon. Today I tried upgrading PHP on my IIS server from a depreciated 5.6.x to a more current 7.2.11. I got everything working fine enough that I got the admin login screen to load well enough, but couldn't actually log in to the system. Couldn't really find anything helpful in the browser's developer console, error messages or such.

Does anyone know if any specific modules have to be enabled so as to get LS 3.x to function with PHP 7.2?

Currently my extensions look like this:

;extension=bz2
;extension=curl
;extension=fileinfo
;extension=gd2
;extension=gettext
;extension=gmp
;extension=intl
extension=imap
;extension=interbase
;extension=ldap
extension=mbstring
;extension=exif ; Must be after mbstring as it depends on it
extension=mysqli
;extension=oci8_12c ; Use with Oracle Database 12c Instant Client
extension=odbc
extension=openssl
;extension=pdo_firebird
extension=pdo_mysql
;extension=pdo_oci
extension=pdo_odbc
;extension=pdo_pgsql
;extension=pdo_sqlite
;extension=pgsql
;extension=shmop
;extension=snmp
;extension=soap
;extension=sockets
;extension=sqlite3
;extension=tidy
;extension=xmlrpc
;extension=xsl

The earlier extension php_mysql.dll has been removed from PHP7.

Or do I perhaps have to make changes to the LimeSurvey config itself when upgrading PHP?

Thanks for any helpful tips, and I hope you all have a nice weekend coming up!

extension=fileinfo , extension=gd2 and extension=exif

Else : maybe something with session, activate debug mode and check what session is created using a developper tool

Hi again, and thank you DenisChenu for your reply!

I finally got it to work by copying the configuration rows from the earlier PHP 5.6.x installation which was done through Microsoft WebPI:

[WebPIChanges]
error_log=C:\PHP_72\phperror.log
cgi.force_redirect=0
cgi.fix_pathinfo=1
fastcgi.impersonate=1
fastcgi.logging=0
max_execution_time=300
extension_dir="C:\PHP_72\ext\"

You should check if tokens are working. If you don't have OpenSSL extension activated, you will run into issues when using PHP 7.2 under windows.
