Hi
Welcome to IW forums
You could search the forums for your answer but to save you time, please see this post, which shows the position of the php.ini files you may want to change, as you have not stated which PHP version you are looking to change
You simple then edit using vim or any text editor the correct php.ini file and locate the short_open_tag and change it to on from off
save and restart php packages (probably best to restart from within nodeworx, system services, web server, restart all php-fpm packages)
If you are not sure about php.ini, please do not change any settings as you could stop or weaken things
Many thanks
John
