500 internal server error – WordPress Problem

500 internal server error – WordPress Problem
I don’t know why, but occasionally I get “500 internal server error” in WordPress”. Sometimes the nature of the error is also weird. Just few days back I was trying to give my online Bengali Magazine Palki a new look using the “WPFULLSITE” theme. Guess what I started getting 500 internal server errors in WordPress. The problem was odd. I could edit most of the pages and posts, but when I was trying to edit my most recent PAGE, I started getting the “500 internal server error” problem. I began to think —

What I did?

  1. I changed the theme.
  2. I added few plugins such as “post views”, “post-ratings” and so on.
  3. I edited post.php, single.php, index.php files so that the plugins could work.
  4. Updated 2.7 version to 2.7.1How to Fix?
Check 1:
Well first thing that you should check is for the .htaccess file. In case you detele it unintentionally, the 500 internal server error would apper.
Check 2:
Is it a theme issue? Just change to a different theme and see if the problem persists. I had some odd theme problems before.
Check 3:
Is it a plugin issue? Start “Deactivating” plugins one after another. After each plugin “deactivation” go back and see if the 500 internal server error is still there. If you are lucky, you should see that after deactivating one particular problem, your site is running smoothly.

If you still cannot solve the problem, file a ticket to yout host suppprt. You can also create a post at WordPress Support forum or do a quick search there to see what others are saying.
So far, in last 3 years, 99% of 500 internal server error problem in my wordpress sites came from some PLUGINS. So, I believe this post could be useful for them who are just starting to use wordpress.

If you had the same problem and you solved in some other way, please let me know. I would like to add more solutions to one of the most commonly faced problem in WordPress.
