This issue just popped up in the last few weeks for me with Tribe Events Calendar.
When both ACF and TEC are activated at the same time, date and time picker fields no longer work as expected. The pickers don’t appear and the input values change to random dates on blur.
Looking into further details at the moment, but hoping I’m not the only one in the meantime.
WP 6.0, PHP 7.4, Twentytwentytwo, latest versions of each plugin
In the interim, I created an
mu-plugin that disables Tribe scripts on a given page:
This fixed the immediate issue for me.
The events plugins is likely loading a different version of select2, or even loading select2 twice, either could cause the issue. Select2 loading can be turned off on ACF https://www.advancedcustomfields.com/resources/acf-settings/
Yeah, that’s more than likely the issue. I’m guessing this has to do with a recent TEC update, but have yet to fully test that theory.
