Installation impossible

Ok, try this
error_reporting = E_ALL & ~E_STRICT

NOTE: this will not work if some other component or extension changes this to E_ALL

Also make sure that inside Joomla Global Configuration you have error reporting set to OFF

Thanks ggppdk, but after this modifications, and restart EasyPHP, all the error messages are still there ...
Anyway it was just for a few extensions tests on localhost. I will soon start the website online, on a temporary domain name.

But of course, it would be easier to make my tests on EasyPHP.

use wamp serveur or serveur2go (a joomla version existe)

J'utilisais wampserver depuis des années, et puis une mise à jour n'a pas voulu fonctionner, malgré différents ajustements.
L'installation de la dernière version de EasyPHP a fonctionné immédiatement, avec Joomla 2.5.9, et 3, Prestashop, Hikashop, Opencart ... jusqu'à l'installation de Flexicontent.

v2.0.0 has cleared many PHP strict warnings (more than 100),

i am afraid of clearing PHP STRICT warning in v2.0.1 because of high number of small changes (100-150 more strict warnings to clear?) may result into 1 or 2 places getting broken

Hello,

Upcoming v2.0.2 (next few days) cleans more PHP strict warnings and offers huge speedup in content listings (category etc) on large sites 10000+ per category (we want to make flexicontent high performance for large sites despite of its features)

v2.0.3 will have all PHP strict warnings cleaned and some minor-medium performance impovements finished

Also note that flexicontent frontend will work smoothly with Joomla's full page caching (system cache plugin) enabled !!
