Wordpress – 3.5.1
Event Espresso –
Event Espresso – Calendar – 2.0.4
Event Espresso – Recurring Events – 1.1.7

When Upgrading Event Espresso – Calendar I am getting the following Warning.

Warning: ucwords() expects parameter 1 to be string, array given in /home2/saltmine/public_html/wp-content/plugins/event-espresso/class/pue/pue-client.php on line 80

I have tried to updating Event Espresso & Recurring Events to the latest version manually but they are not updating. In the admin panel under the plugin I get the following message for the each plugin.

There is a new version of Event Espresso available. View What’s New with version You need a valid Site License Key to enable automatic upgrades. Your current membership level does not allow automatic upgrades on more than one domain. Please log into your account to manage your Site License Keys or purchase a support license now.

Not sure what to do?

Hi Bart,

Both the version of WordPress and the verison of Event Espresso you are currently using a rather outdated.

Personally I would copy the site locally (or to a development server) using a plugin such as Duplicator and run all the updates there BEFORE updating the live site, you may find issues with your sites theme or other plugins when you update WordPress. So testing this locally first and resolving any issues there is your best approach.

So I’m going to assume we are now working locally and do NOT recommend doing this live until you have tested all is ok.

I would start by creating a full site backup. There are multiple ways to do this manually or via plugins. We have a guide posted here on how to manually back up:

Which ever method you chose be sure to back both the website files (all of them) and the websites database. This is very important and should not be skipped, especially when updating from such outdated versions such as these.

Once you have a backup made I would start by updating WordPress.

You can do this by going to Dashboard -> Updates and following the on screen instructions for WordPress One-Click updates.

**Be aware, depending on your current plugins/theme you may find some plugins will stop functioning correctly or your theme may also run into issues, you can check if those either have those also have updates but ultimately this will depend upon the Theme/Plugin developers.

Next you’ll want to manually update Event Espresso and each of its Add-ons. We have a guide post here:

Basically download the latest version from your Account page (as you are currently using an older version of Event Espresso 3 then 3.1.36 you’ll need to update EE3 to the latest BEFORE installing EE4)

De-activate and delete the current version you have installed, then manually add the latest version using Plugins -> Add New -> Upload.

It is the same process for the plugins.

However, you currently have a Personal License which does not include the Recurring Events Manage Add-on so you will not be able to update this currently. (1.1.7 may not function correctly with the latest version of Event Espresso)

Once you have tested this works locally and that all other plugins and your theme still functions correctly (they may also need to be updated) you can follow the same process on the live site.
