I do believe we have come up with a "solution" to the issue, but I think there a question that needs to be answered to determine if this can be marked "solved".
Can that direct php file access requirement be eliminated?
Personally I would prefer to not have an exception rule in place. As such my prefered solution would be to have the direct php file access resolved in the gantry framework for this to be considered solved.

I mean, it looks like you've narrowed it down to a conflict with Admin Tools .htaccess Maker
I'm not a developer, but RT does not typically make production code changes to support other 3rd party extensions

Well that was our assumption. We are less confident with this issue being a conflict with admintools .htaccess maker after reviewing the servier logs from the past weekend.
To eliminate the possibility of the issue being a conflict with admintools .htaccess maker we are adding the following lines to the .htaccess file, this will test exceptions against all files listed in the stack trace. We hope this resolves the issue, but we will monitor over the next week to see if it comes up again. If the issue persists, we will try switching to the core joomla .htaccess file to test full conflict status with admintools .htaccess maker. Assuming the issue persists with the core joomla .htaccess file, I will see if we can narrow anything else now and a possible root cause. Personally I'm less confident about what could be causing the issue, and more wondering what is triggering it, since there is no "referer" information to go off of in the error log.
RewriteRule ^libraries\/joomla\/document\/error\/error\.php$ - [L] RewriteRule ^libraries\/joomla\/document\/document\.php$ - [L]

Re: Uncaught exception 'RuntimeException' Unable to load renderer class
Posted 10 years 4 months ago- Our test with the additional exceptions did not resolve this issue. We are now moving to testing with the default joomla .htaccess file to eleminate admintools .htaccess maker rules as a source of the issue.

Hello
some extensions will raise 403 or 404 execeptions , will ... format is 'raw', or other non 'html' formats !
e.g. typically format is raw for ajax calls, etc
i don't think that asking the framework to render an error page while format is raw is correct !!!
but anyway RocketTheme needs to check inside the template if format is raw because it is calling CLASS methods that do not exist when JDocument format is 'raw' or is 'feed' or 'json' or 'xml', etc ...
To fix this in J3.x, add at the top of the error.php of your template:
$_format = JFactory::getApplication()->input->get('format', 'html'); if ($_format=='raw') { die('Execption with ERROR code:'.$this->error->getCode().' thrown by --RAW-- format URL: '. JURI::current()); }
similar checks should be if format is 'feed', 'json', 'xml'
e.g.
if (in_array($_format, array('raw','feed', 'json', 'xml'))) { // do something differently } -

Hello
i forgot to mention to see how the PHP fatal error occuring inside your browser by the current error.php of the template, because now you only usually get it inside the error_log files
do this:
1. get any invalid URL of your website
2. add to it to ?format=raw or (&format=raw) ... or ?format=json or ?format=xml
again it is probably bad idea by extension to throw such error while format is non HTML but it is good if check is added inside the error.php because the current PHP fatal error is misleading and provides not info of what happened
Maybe this is better ? (anyway template developers looking into this, will probably get better code):
(--ADD the code after the check if $this->error isset)$_format = JFactory::getApplication()->input->get('format', 'html'); if ($_format!='html') { // catch ALL non html formats, or maybe output special e.g. if xml output XML ?? die( 'Exception with ERROR code:'.$this->error->getCode() .' Thrown by --"'.$_format.'"-- format URL: '. JURI::current() .' Error: '.$this->error->getMessage() ); } - Last Edit: 9 years 7 months ago by George Papadakis.
