From LimeSurvey Manual
To increase the memory limit to 128M you could also try adding:
- memory_limit = 128M to your server's main php.ini file (recommended, if you have access)
- memory_limit = 128M to a php.ini file in the LimeSurvey root
- php_value memory_limit 128M in a .htaccess file in the LimeSurvey root
