I'm a beginner in this area. I needed to upgrade php to I can upgrade MediaWiki and add Visual Editor extension, ultimately. I upgraded php from 5.3.3 to 5.6.27 with a success message. But, my wikisite will not come up and I get a 500 error. Looking further I found that php was giving an error like configuration option "php_ini" is not set to php.ini location for module intl. I used pecl to uninstall and re-install intl and got to the point where there is no error returned. But, my wikisite is still not responding.
Could anyone give me some ideas about how to debug what is wrong and fix it that a beginner would be able to understand??
I appreciate any help!
