Super Joe

First off, I have no affiliation with the fine people who create The Events Calendar – I’m just someone who stumbled across your post and wanted to help. Secondly, I am struggling to interpret exactly what you’re saying in your opening post. However, I am wondering if there’s something lost in translation here.

Xylus Themes offer a premium plugin called “WP Event Aggregator” which I believe is what you have purchased. The Events Calendar is free to use, but can be upgraded to The Events Calendar Pro or can be extended with premium add-ons. One of these premium add-ons is called “Event Aggregator”. To be clear: these are two completely separate products by two different developers with a virtually identical name.

I don’t believe your problem has anything to do with The Events Calendar. Without your installation in front of me, I cannot say for certain – but evidence suggests you’re trying to get two plugins to work together that are simply not designed to do so. It may be that you’re putting the license key for the Xylus Aggregator plugin into The Events Calendar’s add-on of a similar name, hence the error message regarding an invalid license. There also appears to be confusion around what is free and what isn’t – The Events Calendar is free, but the Pro version and/or its add-ons are not.

Everything is functional. I am now at 3.3.2! Thank you once again for your help. Though as simple as the problem may have been, I still can’t thank you enough for your assistance.

Alright, I will do. Though we’re not at the end just yet, I just want to thank you for the time you’ve dedicated to my problem this afternoon. It is much appreciated.

I may seem overly cautious at this point, but do you suggest I continue my manual incremental upgrades or go straight for an automatic one?

Well, I won’t actually be using that theme when I finally get to the latest version of WordPress. I’d rather safely assume it is, if you understand.

My upgrade from 3.1.4 to 3.2 was successful. Now I’m really stuck as to what the problem may be. I’m tempted to try an automatic upgrade to the latest version from here, but I’m still unsure. Suggestions?

Well, I’ll revert to Twenty Ten for the purposes of the upgrade. I’ll try it now.

With debug enabled, this is the error that is shown upon enabling Twenty Eleven 1.2:

“Fatal error: Call to undefined function is_multi_author() in /home/linweb02/r/reactiontime.co.uk/user/htdocs/wp-content/themes/twentyeleven/functions.php on line 583”

I acknowledge that this isn’t the latest version of the theme, but it is the one that came alongside 3.1.4.

Before. I thought I’d mention it in case it had significance.

Is there any reason why changing to Twenty Eleven would result in a completely grey page once I go to the homepage? Empty, just grey.

EDIT: Twenty Ten works fine. This a problem?

Alright. I had disabled plugins already, but I shall try the default theme and then attempt an upgrade. I’ll let you know how it goes.

I cannot seem to access server error logs through my web hosting control panel.

I did the PHP test, and I have version 5.2.17.

No error messages, except on Chrome in which it mentions a server error. No pages are accessible, and with the automatic update, it doesn’t even get to the page (update.php, is it?). I have to roll it back to get the website running again.

I don’t know the version specifically, but I ran a plugin to check it was compatible and it says everything I was running off of was no trouble at all – all up to date.

EDIT: I have just successfully upgraded from 3.1 to 3.1.4. Hesitant to try 3.1.4 to 3.2, but will do after some more feedback.

Same computer, and I’ve tried different browsers. Though a colleague of mine with the Author privilege is experiencing the same problem in a completely different country, so yeah, different computer there.
