Solved The server’s temporary folder cannot be accessed.

After my web hosting provider upgraded their servers from Apache/PHP-FPM to OpenLiteSpeed I get the following error in webtrees control panel:

The server’s temporary folder cannot be accessed.
sys_get_temp_dir() = "/tmp/"
ini_get("open_basedir") = "/var/www/virtual/myhostname/htdocs:/var/www/virtual/myhostname/phptmp:/usr/local/lsws/lsphp83/:/var/www/helpers/:/dev/random:/dev/urandom"

I'm running webtrees 2.1.20 and was at the time my web hosting provider made the above upgrade to the servers. The above error came directly after the upgrade from Apache/PHP-FPM to OpenLiteSpeed. LiteSpeed 8.3 is running on the server with webtrees 2.1.20 and this is the only problem experienced so far with the upgrade.

I've contacted my web hosting with support in solving this (included the error code in my request) and their response was that I need to change the temp dir request from tmp to phptmp. Is it possible to change this within webtrees without directly changing the software code, i.e. other better options to solve this?

Any help to solve this would be appreciated.

ask your provider how to do this best for your environment,
or simply change/set in .htaccess .
or set an environment variable with a php-file.
 

Issue solved when my hosting company inserted the necessary parameter in the sys_temp_dir (local value) of PHP which was blank and caused the error.
