To remove this notification, go through $internal_c/lang/config.php file
find the code around line number 7469 this code looks something similar to this.
'try_number' =>
SK_ConfigDtoObject::__set_state(array(
'config_id' => '208',
'config_section_id' => '63',
'name' => 'try_number',
'value' => 5,
'presentation' => 'integer',
'description' => NULL,
'php_validation' => NULL,
'js_validation' => NULL,
)),
Here, set the value to zero, like
'try_number' =>
SK_ConfigDtoObject::__set_state(array(
'config_id' => '208',
'config_section_id' => '63',
'name' => 'try_number',
'value' => 0,
'presentation' => 'integer',
'description' => NULL,
'php_validation' => NULL,
'js_validation' => NULL,
)),
Also set the lock_stamp attribute to zero, like
'lock_stamp' =>
SK_ConfigDtoObject::__set_state(array(
'config_id' => '206',
'config_section_id' => '63',
'name' => 'lock_stamp',
'value' => 0,
'presentation' => 'integer',
'description' => NULL,
'php_validation' => NULL,
'js_validation' => NULL,
)
And the last step is, in the config table, search the config_section_id (here it's 63, see above code) and change the values of 'try_number' and 'lock_stamp' attributes to zero.
This should solve your problem....
