If you are skittish about trying the method I laid out, you probably will not get the problems fixed. If I remember correctly, the site is overloaded with plugins. The practical limit is about 10, but that site was way over that number. WordPress loads every plugin whenever a page is requested, whether the plugin is activated or not. That can easily drag down the performance. Old plugins and themes that have not been updated cause a lot of problems with incompatible code and conflicts.
Most likely the only way you are going to fix the problems for the long term is to bite the bullet and update everything, including the theme.
Yes, the site has now 22 plugins after adding the last one. I could get rid of a few of them but I don't see me getting it down to ten.
Update. I hired some to try to fix the site.
This is what he said.
I just finish checking your site. Unfortunately I'm unable to fix the problem. I found out that its an issue with your theme because I updated wordpress along with all plugins then deactivated all plugins one at a time and the problem is still the same. However I use other themes and the editor is working fine. So, I believe the problem is conflict with jquery & js that your theme use.
I think you can find someone at freelancer who can fix your theme. Just post a project and let them know the problem with the editor and you need your theme's function.php to be check along with the jquery & js issues.
I will give you a refund when I get to my computer at home.
My money was refunded.
Now everything is current including wordpress. :)
I will now try freelancer to see if I can find someone to fix the theme. Unless some knows someone from here that could do it.
Got any advice on that, Like what would be fare to pay for this project?
Given what I have seen with the quality of freelance work over the past couple of years, I need to caution you about this. The overwhelming number of people offering their services will not know what to do, other than to build a new theme. Anyone who is not qualified to do this can mess your site up horribly. From my perspective, I think you will be better off investing in a new theme that is compatible with current version of WordPress. A lot of the sites that sell themes are also currently selling buggy garbage that is not fully compatible with current WordPress. You might want to look at the themes from a site like iThemes. They have a very good reputation. The crap themes that GoDaddy offers are really bad. They are farming it out to an overseas company that builds beautiful looking themes with horribly written code.
Also, find a way to cut the number of plugins down to less than 10. The problem might not be the theme at all. You are using way too many outdated plugins. Even popular plugins, such as Contact Form 7, run into compatibility issues with other plugins.
If you still want to manually modify the welcome e-mail core code, thse threads may help.

Here is a solution that may work. The functions.php file the author refers to is in the theme directory. It is not a core file. That is where you are supposed to override core functions. WordPress :: WP Questions
I know you probably do not want to hear this or cannot afford it right now, but my recommendation is to start over with a new theme design. It may be much easier and less expensive to start out fresh and clean. All of your content, categories and embedded images should move over to the new design. Current versions of WordPress are supposed to save the configurations for each theme separately, so you will have to reconfigure custom menus and things like that.
I will work on cutting plugins down. There are a few that I don't use that much. I will see if that helps any.
But I will need to find someone to fix this theme. Not going to redo everything.
