The calendar no longer works with WP5.5 as jquery has been updated and the plugin uses depreciated jquery that has been dropped. However, you can still use it by adding the WP plugin ‘Enable jQuery Migrate Helper’.

You can also upgrade to PHP7.4 by commenting out the function at the bottom of widget-contributors.php in the inc folder

function form () {
_e(‘No options available.’, AEC_NAME);
}*/

These are just hacks to keep this great plugin working on your site for now!

I have now worked on a better solution:
1.Goto
https://code.google.com/archive/p/simplemodal/downloads
download jquery.simplemodel.1.4.4.min.js
rename it jquery.simplemodel.1.4.3.min.js

overwrite it in your WP plugins folder ajax-event-calander/js
2. Goto
https://plugins.jquery.com/jgrowl/
download version 1.3.0
unzip and copy jquery.jgrowl.min.js into WP plugins folder ajax-event-calander/js
overwriting old version

These two updates were written by the plugin author, but I guess he didn’t update the plugin with them, before stopping his support.
For some reason still need the ‘Enable jQuery Migrate Helper’, as the calander crashes without. Will let you know if I find the answer to this!!

Happy Days!!

Hey Karen

I’m sorry to be a pain, I’m trying to get caught up here. I did both of those things and still don’t seem to be able to make it work.

I downloaded the files you pointed to, changed the name as suggested, and wrote them to the directory.

I then also installed the plugin. Is there anything else I’m missing, etc?

I tried the PHP7.4 commenting out thing, and then didn’t work, it made the calendar not even show a single entry per month, so I edited it back as it was.

Any help would really be appreciated. I’ve used this calendar for years and years, I’d hate to lose it due my complete lack of knowledge about such thing.

The calendar on my site is at https://www.expeditionsalaska.com/calendar/
Thanks in advance.
Cheers

I did Karens (@karen-turner) upgrades, site here:

I love the plugin and have a couple of sites running it. I have been doing my own Jquery hacks to keep it going but this error I cant seem to fix. Also installed the Migrate helper plugin.
