I am getting 500 error "Internal Server Error" when I type in my domain. I called customer service and they said that my site has reached it maximum use of memory and therefore the cloud system generates this error. I have never heard of this before. What they said is I can get this error because of either higher:
- Memory Usage
- CPU Usage
- MySQL usage
They recommended to tweak the website and remove plugins etc to get rid of this error or upgrade. Things have not changed much here and we didn't do any major upgrade either. What should I tweak if any? Has anyone come across such error. We are hosting with lunarpages and using PHP 4.7 (it is an older site).
Would upgrading to PHP 5.3 fix things? Interestingly if I go to
mydomain.com/index.php it works.
