mb_internal_encoding is a non default extention meaning that it is not active by default on the server.
You will need to contact your host to resolve this issue.
I have contact my host, they said i will change my pack windows into linux.
It's done.
Now i have a new error. After upload i have error 500.
I have change in config.php:
define('OW_DEBUG_MODE', true);
define('OW_DEV_MODE', true);
But nothing happened...
Please go to /ow_core/plugin_manager.php file and find this line:
@include ( OW::getApplication()->isMobile() ? $value->getMobileDir() : $value->getRootDir() ) . 'init.php'
remove "@" and save the file
then refresh the page, you must see an error then, copy the error here, so we could assist you and undo you changes to the plugin_manager.php file
thanks but my host take care of the problem today, they just say: we must change htaccess, it isn't correct...
thanks anyway for your help :D
