500 Internal Server Error

Hello,

I got a few problem here. Why my website always show 500 Internal Server Error.
It always happen, almost everyday.
I've already discuss this with my hosting provider.
Their answer is:

Hi,

Your website script is overuse the server resources.
I have restart the services, your website can be access now.

If happen again, please check your website script as it probably is cause by the website theme or plugin.
Thanks.

But i don't know how to track which themes or plugin that overuse the server resource.
That hosting has 1 main website and 2 on addon domain.
Here the other answer from my conversation:

"Hi,

I have restart the services, please try again.
We are not sure which script or plugin causing the problem.
You have to check it by yourself.
Thanks."

"Hi,

I believe the memory usage is cause by your main domain kadkahwinonline.com.
We can't trace which script is causing the problem, the server log only show your main page overuse the resources.
Thanks."

Please help me

Normally it's a database connection issue. Either you have low traffic and the database goes away, or you have high traffic and too many connections.

This will also happen on shared hosting if you are running auto blog plugins/scripts and other things like social sharing plugins as these have a high impact on CPU usage.

I think it has medium traffic but got too many connection.
Okay thanks, i will check sharing plugin. I think i got 2 social sharing plugin including Jetpack sharing plugin.

In cPanel towards the bottom find Cron and look to see if something is running (at bottom).
Are you auto posting? WPRobot wink wink
Not knowing what plan you're on...

Can i redirect that website first to Facebook fan page? (for the time being)
I'm not using any autopost. That website is e-commerce website.

Is it a e-com using amazon plugins? If so that will be your problem. I used to find turning off the amazon auto update info option to help. For social sharing try and have a few second delay between to help.

I got a report:

Hi,

After check further, we found your .htaccess file entry is causing the error.
Please fix the entry in .htaccess to solve the problem.
Thanks.

Can i know if .htaccess got auto update features? Because after i check the .htaccess, the code that in that file wasn't the same with the one that i use before.

This is the code that i'm using:
