Switched Server Provider Now Fatal Error Solved
« on: September 11, 2017, 08:39:21 PM »
pennlake.us

Today I switched server providers - Both use c-panel and I did a complete backup of my site and then well basically handed it off to the other provider, also uses c-panel.

So Using PHP 7.1or 7.0 I get this Fatal Error:
Fatal error: Uncaught Error: Class 'DOMDocument' not found in /home/hogan2/pennlake.us/get-aqi-rss.php:18 Stack trace: #0 /home/hogan2/pennlake.us/get-aqi-rss.php(8): getAQIdata('http://feeds.en...', 'realtime') #1 /home/hogan2/pennlake.us/ajax-dashboard6.php(111): include_once('/home/hogan2/pe...') #2 /home/hogan2/pennlake.us/index.php(98): include_once('/home/hogan2/pe...') #3 {main} thrown in /home/hogan2/pennlake.us/get-aqi-rss.php on line 18

Using PHP version 5.6 I get this error:
Fatal error: Class 'DOMDocument' not found in /home/hogan2/pennlake.us/get-aqi-rss.php on line 18

My original server used PHP version 7.1

So, as most of you know, this is way above me, so any help would be very much appreciated.

This is a missing class, classes are defined by scripts so to me this looks like rather some script hasn't been copied or this one is corrupted (incomplete)

Thanks Jachym, and by the way your Meteotemplate seems to have made the transition just fine!!!

With your info I think I will start replacing the scripts, perhaps something will get corrected.

Thanks for the response!!

First try re-uploading:

get-aqi-rss.php

if that does not help, post here the script you are using

It seems essential parts of PHP are not installed / available by your provider.

This is the official Saratoga test script
http://www.pennlake.us/check-fetch-times.php?show=info
which shows missing essential items which all providers normally supply:
function json_decode is NOT available
Without json support no data can be retrieved from NOAA/NWS, no data for earthquakes, no data for the Steelseries a.s.o.

Current GD status:
GD support: NO

GD support is essential for a lot of images which are dynamically created.

===
The versions of the Saratoga scripts are current, no problem there
http://www.pennlake.us/check-fetch-times.php?show=versions

===
The missing DOMDocument class form your first post is also not found for the same reasons.
This is from the PHP manual:  http://php.net/manual/en/intro.dom.php
Quote
The DOM extension allows you to operate on XML documents through the DOM API with PHP.
This is from the  http://php.net/manual/en/dom.installation.php
Quote
This extension is enabled by default. It may be disabled by using the following option at compile time: --disable-dom

So your provider choose to disable all DOM functions from the PHP 7.1 version you are using.

You should check with your provider why your php version is missing essential parts which your scripts need.  All Saratoga (and Leuven) template users need and have these extensions.
