We would be the more than happy to provide insight into the contents of your site’s error log. Comparing the error_log before and after loading the site, I noticed a large number of new lines being generated each time. A summary of these has been provided below:

After some review, it looks like these were a result of a php.ini file in your site’s document root. It appears it was causing many modules to attempt to load twice, producing the output seen here. I’ve renamed this conflicting php.ini file, and the same errors above are not appearing in the error_log when the site is loaded now. I’ve also attempted to enable WP DEBUG mode, but this did not produce any additional errors that we were able to observe. It does not appear that WP DEBUG mode was able to identify any errors while enabled.
