Cannot exit debug mode - site is live - Joomla! Forum - community, help and support

about 10 minutes ago purposely put on debug mode. returned configuration settings turn off , configuration panel has changed , can't save in screen or turn debug mode off! it's worrying site live , weekend, have high traffic.

other things, such configuration components, modules, plugins, public pages fine , functioning normal. joomla site , installation in subdomain. perhaps important looking @ this.

i see 500 error on screen , error message in error console below page :
jdatabasemysqli::query: 1054 - unknown column 'alias' in 'where clause' sql=select id j25_assets alias = 'root'

i have never seen problem before. first time using debug in 2.5 version after upgrading 1.56.

please see file attached.

version joomla! 2.5.8 stable [ ember ] 8-november-2012 14:00 gmt
php version : 5.3.17-1byte1squeeze1

i notice configuration file keeps defaulting unwritable mode. put writable no change.

can help?

thanks,
liz

not sure problem is, in order site out of debug mode, use ftp find configuration.php file in site's root directory , change line

code: select all

public $debug = '1';

to

code: select all

public $debug = '0';

it debug mode causing these strange things , turning off through ftp return config panel full working order.
