zounds

Argh – I’ll mark this as resolved, so simple.

Edited class-ai1ec-calendar-controller.php

Changed

// Point script to AJAX URL – use relative to plugin URL to fix domain mapping issues

‘ajaxurl’ => site_url( ‘wp-admin/admin-ajax.php’ ),

to

‘ajaxurl’ => ( ‘/wp-admin/admin-ajax.php’ ),

Was just a matter of finding it.

I’ve found what the problem is.

Externally:

[03:46:42.343] POST https://website.meopham.school/wp-admin/admin-ajax.php [undefined 1ms]

So the external URL isn’t being read. must be a wordpressurl/wp-admin/ hard coded somewhere, rather than just /wp-admin/

Cheers Alex – saved me plenty of frustration, I’d never have dreamt of looking there again (I’d clicked on screen options once before elsewhere and it only had an accesibility option).

Thanks!
