I just inherited care and feeding of a website that uses JEM 2.2.3 on Joomla 3.9.1 with php 7.0.33 . I've never used JEM before and didn't set this website up.

JEM is configured so that events can only be created/modified on the backend by Joomla users. When Joomla users try to add new events or modify existing events, they simply get a blank page. I'm a superuser and I get the same thing: just a blank page.

For example, I click on "Add event," and it opens this URL : $WEBROOT/administrator/index.php?option=com_jem&view=event&layout=edit , but all this is is a blank page.

I turned on Debug System logging but couldn't find any error messages. Contents of jcontroller.log.php:

When I try to edit event ID 102, this is all that is written to jcontroller.log.php :
#Fields: datetime	priority clientip	category	message
2019-11-02T19:10:31+00:00	INFO 198.48.224.207	controller	Holding edit ID com_jem.edit.event.102 Array (     [0] => 102 ) 

Something else extremely weird: when I do "view source" on the above blank page, the source is all JS and it seems to stop in the middle of a script:
<script type="text/javascript">
window.addEvent('domready', function(){
	checkmaxplaces();
.... [ snip many lines ] ...
</script>
<script type="text/javascript">
Joomla.submitbutton = function(task)
{
		if (task == 'event.cancel' || document.formvalidator.isValid(document.id('event-form'))) {
			Joomla.submitform(task, document.getElementById('event-form'));
And that's it. It just stops there on line 100, in the middle of a script. Is there some reason JEM would only deliver the first 100 lines of the page???

Any help appreciated.

Thanks,
Nat

Hi, I am only a user of JEM. But I can't reproduce your problem. If you csn try with lnly with official templates and plugins. Sometimes other tempöates create interferences.

For me it seems that your have not configured the permissions correctly.
Eventually on line 100 is the php check for permissions, if you don't have permissions, it will stop. - Just some thoughts....
Take a look at the responsive version of JEM: The Responsive JEM
