Tried an import on PHP 7.0.5 / Joomla 3.5.1 using latest CSVI 6.5.6 and got the following fatal error in the server
[Mon Apr 11 16:02:37.911351 2016] [fcgid:warn] [pid 22514] [client 62.38.74.252:54541] mod_fcgid: stderr: PHP Fatal error: Cannot use 'String' as class name as it is reserved in /home/****/public_html/libraries/vendor/joomla/string/src/String.php on line 19, referer: https://www.quality-tuning.eu/administrator/index.php?option=com_csvi&view=import
Hope you have a clue on this!
Rgrds,
