Preguntas frecuentes

Important notes for users who upgraded to 20200902 and experience differences

The 20200902 update makes it possible to display private and public Google calendars at the same time in the same widget, shortcode or Gutenberg block.
This update makes the plugin also more secure. Though tested thoroughly it can be possible you experience a difference. Here are some possible differences and ways to solve them.

  • Public calendar isn’t showing anymore: this can happen when you display a calendar that you also have added to your Google account but didn’t select in the plugin settings page.
    The solution is either remove the calendar from your Google account or select it in the settings.

How can I override the calendar look?

Create a child theme and enqueue a css file with a dependency on pgc for example:

wp_enqueue_style('fullcalendar-override', get_stylesheet_directory_uri() . '/fullcalendar-override.css', ['pgc']);

I get a ‘Token has been expired or revoked’ error

This usually means you don’t have a valid access or refresh token anymore. This can only be solved by manually revoke access on the Google Permissions page and remove all plugin data.

I get an ‘Error: redirect_uri_mismatch’ error when I want to authorize

This means that you didn’t add your current URL [YOURWEBSITE]/wp-admin/options-general.php?page=pgc to the authorized redirect URIs. See the website for more information.

W3 Total Cache

If you use W3 Total Cache and have minify JS enabled, make sure that you do one of the following:
Choose “Combine only” in the “Minify” settings.
OR
Enter the following files in the “Never minify the following JS files” textbox.
Make sure you add the full path to these files from the root of your installation, so if your WordPress website is located in the wordpress directory, this will be (for FullCalendatr 5):

wordpress/wp-content/plugins/private-google-calendars/lib/dist/main.js

And for FullCalendar 4:

wordpress/wp-content/plugins/private-google-calendars/lib/fullcalendar4/core/main.min.js
wordpress/wp-content/plugins/private-google-calendars/lib/fullcalendar4/core/locales-all.min.js
wordpress/wp-content/plugins/private-google-calendars/lib/fullcalendar4/list/main.min.js
wordpress/wp-content/plugins/private-google-calendars/lib/fullcalendar4/timegrid/main.min.js

This plugin has been fantastic for a website I'm working on for a nonprofit organization that uses Google Workspace. I've been able to create individual calendars for a number of groups within the nonprofit and give each group access to create and update their own calendar events, then display all the events on their website in a single calendar, as well as provide individual calendars for some of the groups. With custom CSS, I've been able to style the calendar output to match the website's theme. The support for this free plugin has consistently been timely and helpful.

We all love free plugins, especially ones that don’t charge a dime for “pro” versions or etc. This is one of those: it has some great features, and it is totally free. I will start with the positives to encourage further development, and then list some negatives. The positives are: It does what it says, and presents one or more Gcal’s in a nice, clean, and fast way The initial setup instructions are pretty good, and can usually get you going if you use Oauth for private calendar access There are various display options that give nice flexibility The caching feature is nice, reducing the API calls to Google For free, those are pretty nice. The downsides are several, though: It only seems to operate correctly in Oauth mode, giving access from the wordpress site and all admins therein to All of the calendars on the connected account. I ended up spending a bunch of time using a secondary account that had the calendars I wanted shared to it (and publicly), to avoid potential breach of my private calendars in the main account. I would far prefer to have a supported option to access only public calendars via the API key, but I tried that several times and it would not work. (Plus, the docs say that’s “unsupported.” It conflicts with several other plugins that use Oauth, including the well-written and supported “Use Your Drive” plugin and even Elementor Pro. Specifically, it blocks them from using Oauth to initially connect to external services. So this plugin has to be turned off to connect those, then it can be turned back on. While this is just a “minor inconvenience,” it took hours of wasted time to figure out what was going on. And then a support thread that was opened has been ignored for almost a week about that. Personally, I would rather pay for a plugin and get some real support, than have to wait for ??? amount of time for a fix to a problem like this. If you want any control over the display beyond the default, the documentation is somewhat limited, though after the author's response to my initial review I see there is a helpful examples page. This would solve some of the issues I had getting this to do what I need it to. This is a great plugin. Just beware, there is no upfront charge for this plugin, but if you value your time, there is a cost. It takes more to set up than the typical wordpress plugin (and I've set up 100's over the past 10 years). There are no great alternatives (only one commercial alternative whose install immediately caused a conflict), and this plugin is the main show. So I’ll give it 4 stars. It's great but not perfect.

Excellent implementation of fullcalendar.io for wordpress, with attention to gutenberg. Very rapid support response from the developer. Note to new users: google just changed their API authorization; to display public google calendars, use the private calendar setup instructions on the developer's website. See support thread for more information.
