Thanks.
But i already said that, i already set my domain name is Settings section.
And please i Request you, please see carefully what i say now in bellow. Please.
--When i install AbanteCart to my hosting account- eshopee.meximas.com, in August Month 2014, then in that installation time i have to enter this details--
URL-
Administrator Username-
Administrator Email-
Administrator Password-
Store Name-
-BUT then in that time i have not my Own Domain name, so in that installation time i unable to add my own domain name in the URL section.
But after that, in October Month 2014 i register a own domain name like mydomain.com, and then i parked the mydomain.com in my hosting account- eshopee.meximas.com, and after that i add the domain in Setings section in AbanteCart Admin Panel.
But i still receive Error messages in Error Log of AbanteCart Admin panel in time to time, as- unknown unconfigured domain eshopee.meximas.com, (which is my hosting account).
So i want to add mydomain.com in config.php file of public_html/core/lib;   SO Please tell me, can i do this? And please tell me the proper location in Config.php file to add own domain name 'mydomain.com' in Config.php file of public_html/core/lib?
Please i request you.

I want to tell you one thing.
When i see in error log of admin panel, then i see about- Unconfigured domain name.
And this error message i get from some days (month).
But about this website error mentioned here, there is not any other error message.
And for the Unconfigured domain error message, i post a topic in forum few days ago, about How To Add Url In Config.php, and you replyed also.
And please tell me, can i add my own domain name in /public_html/core/lib/config.php? (Which domain name to access my AbanteCart site, and which domain name i already set in system settings).
If yes, if i can, then in which section i have to add my domain name in the config.php in /public_html/core/lib?
Please tell me that.
I think, if i add my domain name in config.php, then this website error is also solve permanently.
So please tell me Basara.

Ok Basara, i will post here error log of AbanteCart Admin panel.

Hi all.
From a few days, i found a problem with my AbanteCart site.
When i go to visit my site, then a AbanteCart error page is displayed, and says- "There Has Been Error Processing You Request. Please see Error Log in Control Panel"    -etc.
And after 2 or 3 hours the problem is solve automatically.
But after the day, next morning the problem will be happen again.
And i see in error log in control panel, but nothing in there.
And i also want to tell this, i never edit any configuration files, even accidently.
So i need a way to solve the problem permanently.
And i see many posts here about this problem.
But i could not find any idea how to solve the problem.
So please i request you, please tell me how do i solve this problem.
Please tell me as soon as possible.
Because my site is Live for customers. So please help me.
