Webmasters like you and me are ever online – may be from several different devices. Therefore, the site has to be live and it’s the web host’s duty. However, there are many sites that suffer the “500 Internal Server Error” several times during the day. Most webmasters think that it is the host’s fault (or weakness) that such messages are displayed and the site is put down. Although these errors don’t last for a long time, they do annoy the readers and especially the administrator of the site. It doesn’t matter what platform (e.g. WordPress, Joomla, Drupal, etc.) you’re using to set up the site because it doesn’t really have to do anything with the platform.
I can say that because recently, I had a conversation with my web host’s support staff and it was something (not exactly) like the following.
Me: …actually I have a lot of WordPress installations on my server, so can that be the reason why I’m facing too many 500 Internal Server Errors?
Staff: …No, the error has nothing to do with the number of installations of any CMS or software.
Well, then what exactly is the issue? Let’s find out!
The Main Cause of a 500 Error
The main reason is the number of email accounts being run from that server. Yes, that might sound weird but it is the case. Most, if not all, of us, run our custom email accounts through the same server where we host our site(s). Now, for every server, there is a limit to the number of server requests being on at the same time. When the email accounts are used on third-party devices i.e. anywhere except the live online mail, the number of server requests increase. The best example is your laptop/computer. If you’ve set up all your email accounts in iMail or Outlook, the number of server requests will simply increase.
How To Fix (and avoid) 500 Error
The fix is really simple – most email platforms (even on smartphones) have an option of ‘Push Mail’. This means that the mail client is constantly sending service requests to the host asking whether there’s an email or not. Therefore, if you believe that you have a lot of email accounts running at the same time (number can be 5+), then you should consider avoiding the “Push Mail” feature and manually setting the time for the mail clients to refresh. The appropriate time can be 5-10 minutes. This will definitely reduce the number of server requests, also called IMAP or POP server requests, sent to the host.
Recommended Hosts To Avoid the 500 EError
Although it relies much on your usage, the hosts do play some part in handling the error because the limit to the number of server requests at once is decided and set by the host. I would personally recommend buying hosting from some biggest brands like; Siteground, Hostgator, or Bluehost or you may choose any other high-quality normal or cloud hosting provider to get fewer chances of a server error.
