ok, the warning won't be shown anymor by editig the code the way you've shown. But there is another problem: it's not possible to safe any changes in the configuration. It says "Save failed" - without any further information?

First I thought it's caused by the problem caused that warning - but now the warning is gone, but saving fails anyway.

Thanks for help!

Hello,

that problem is only in Configuration page? What about logs? Is there anything about your problem with saving?
I tested it with actual version of Booking and I have no problems with saving configuration.

yes, only in the Configuration page. Here is the part from Logging my try to change Config:

Hello,

that was access.log and it showed me nothing special. What about error.log? There is nothing about problem with saving config?

well, it seems during the installation went something wrong: there is no config-table in the database (found that error by running the site in debug-modus)

Now I've tried to uninstall the component, but that won't work cause of the missing database-table :(
I will try again in the evening when my time is not so rare...


part of the error-log:

Ok, I can not find this table in installation script.

Can you try execute this SQL in your phpmyadmin and then try to save config? Do not forget to change your prefix '#_'.

CREATE TABLE IF NOT EXISTS `#__booking_config` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`key` varchar(100) NOT NULL,
`value` varchar(5000) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `key` (`key`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
