Updating php.ini to work with php 7

php 7 removes support for various php options. If you have directives for these options in your php.ini file, php 7 will not run. Depending upon your error reporting configuration, you may recieve no visual feedback as to the cause of the problem.

You should remove the following directives from php.ini :

asp_tags = On

If you are unsure about a particular php.ini directive, you can "comment out" the line to test. Add a semi-colon to the front of the line then save and upload the new php.ini file. To test, reload the page in question.
