Have you done installation using script installer? or was it downloaded from moodle.org?
in either case, try doing re-install from start, if your current one was from a script installer, do a manual install from files downloaded from moodle.org

Abdul, it'll not be moodle, but php.ini file you'll be making changes in, you have to ask your hosting provider if they can let you make changes to the PHP, in most cases they wont allow, but because you mentioned ability to make changes to I assumed your hosting provider may have given right to amend php at individual level accounts. Usually php.ini files are found at root level of your host folder.
what does moodle implementation has to do with a geographical region? is it banned in your country?
Heather, 500 errors are usually timeout, can you apply what ever is mentioned in this post and see if this works out for you
