Hi Mel,
You can check the available positions in a page by turning on the preview module position setting in template options then appending ?tp=1 in the url(http://take.ms/PkORK).
If this does not work for you, can you provide us the site along with its access so we can check this for you?
Also, you can also let us know which module and position you want to display so we can try it out for you as well. Thanks.

Just to add that I was also having issues getting modules to appear so I tried your suggestion and find that it seems the documentation is all incorrect (perhaps not been updated to match this current release?)
https://stackideas.com/docs/easysocial/administrators/module-positions/event-page-position

Please can this be updated as even using the ?tp=1 option is not ideal as some positions when I look I think it's showing truncated text (plus of course we also pay for the product and expect the documentation to actually be correct!)

Thanks for the input on this Itamar. The reason that we suggest using ?tp=1 in the url is because EasySocial is an extremely huge extension and if I recall correctly, it has over 300 different module positions combined. It's going to be very tedious to maintain all module positions on the documentation.

Having said that, we'll definitely update the docs soon.

Er, you mean to tell me someone creates those positions and defines a name but no where do they write it down?! Please let me that's not how you work!

I do get the feeling you could do with taking on someone just to work on documentation, at least in the short term to get it all up to date.

What I am trying to tell you is that using the tp=1 in the URL parameter, would give you the best result as it is always up to date. I will get our team members to update the documentation page for module positions.

The issue I found with that is it looks like on my display at least, some of the names get truncated so you are not sure what they actually say (see screen shot)

Hey Itamar,

I get what you mean here. Unfortunately that is how that Joomla feature works. You can try highlighting the element, copy and paste in a text editor to see the full text.

For ES module positions, we will update it in the docs as mentioned.
