PHP version for SuiteCRM 7.7.1

Dears,

Could somebody tell me what is the minimum PHP version necessary to run suitecrm 7.7.1?
I just installed crm 7.7.1 with PHP version 5.2 and I found some warnings like:

Strict Standards: Declaration of SchedulersViewDetail::_getModuleTitleListParam() should be compatible with SugarView::_getModuleTitleListParam($browserTitle = false) in /home/proce761/public_html/crm771/modules/Schedulers/views/view.detail.php on line 69

Warning: Invalid argument supplied for foreach() in /home/proce761/public_html/crm771/include/SearchForm/SearchForm2.php on line 380

Warning: Invalid argument supplied for foreach() in /home/proce761/public_html/crm771/include/SearchForm/SearchForm2.php on line 661

Thanks in advance.

with 7.6.X you need at least PHP 5.5 https://suitecrm.com/wiki/index.php/Compatibility_Matrix

Perhaps related (if not, sorry for the hijack).

When upgrading from 7.6.6 to 7.7.1, using the upgrade file, I receive the following message:

The uploaded file is not compatible with this version of PHP:
PHP Version: 5.3.10-1ubuntu3.18

Mind you, I’m running on suiteondemand AND 7.6.6. gives no issues atm.
