As you have noticed I'm not a programmer.
Well, I got it work when I disabled Falang language system. Bad point is that multilanguage is not available.
How to get it work with Falang?

I understood it's possible?
Thank you.

Ok, I am sorry. You can enable falang. This is not the problem.
Then go to Joomla Global Configuration:
System -> Global Configuration -> tab Server -> Error Reporting set to none.

IIf it will not help, then contact your server hosting and they should be able to disable strict standards reporting.

I have changed error reporting to: none. It doesn't help. It hides error reporting doesn't solve the problem?
Here is my site: www.papinniemicamping.net
Artio var=bookign (last link)
When I disable falang database driver it works. I need also multilanguage.
Is only change try to use Joomla default multilanguage system..that endless copying? Falang was too easy to be true :/

If it doesn't help, then you can contact server hosting to solve this problem. I am not sure what php version do you have, but if you do not disable strict standards in php 5.4, then it will show all strict standard messages.
More about problem on: stackoverflow.com/questions/9983286/disa...standards-in-php-5-4

Falang use router.php to parse url addresses, so it can translate your content easily because it understand what page you see. If you disable falang, then router.php from booking is not used. For this reason there is no message.

You can use falang and router.php will work, but you have to only hide those messages.

Php version is 5.4
My server hoster changed settings. Same error logs :( and booking not working (when falang enabled).

Hello,

what do you mean with "not working"? That there are displayed strict standards or you have some problems with functionality?

If you look on (in administration part of website): System -> System Information -> tab PHP information
and find error_reporting, what numbers are there?
