Fatal error: Call to a member function getTimestamp()

[soderlind]

Which PHP version do you have ?

[dannykater]

I have the same problem. Date time picker suddenly stopped working. I think this happened after changing Wordpress from EN to NL.

Any solution already?

[soderlind]

@dannykater You just changed from EN to NL, i.e. it's the same installation ? Reason I ask is if it's a different installation and the PHP version differ (and PHP is less that 5.3), it can be the problem.

[soderlind]

btw .. if you'd like it to work as in 2.0.5 (not saveing date and time as a timestap), you can set this where you create the field.

NOTE, this will mess up your existing date and time values since they are in timestamp format.

[dannykater]

@soderlind Yes it's the same installation. Changed language in wp-config.php and then updated to NL version.

It is working with timestamp on EN. So i dont see a reason to change that. Unfortunately it doesnt work in NL.

For some reason the "Date and Time Picker" doesn't change to NL language. The language is available in localization folder. Maybe it's got something to do with this?

[dannykater]

@soderlind OK another update. I just changed the language to EN in the NL installation. And now the Fatal Error is not there anymore. So my conclussion is that the problem is related to the WP_LANG.

On NL it's not working. On EN it does. Regardsless the installation.

On Post->Add New (if it's where you have your date and time picker field), please do a view-source.

Search for timepicker_objectL10n, are the monthNames etc in Dutch?

Also search for acf-field-date-time-picker/js/localization/, if you find it, is the file?:
acf-field-date-time-picker/js/localization/jquery-ui-timepicker-nl.js?ver=2.0.8

[dannykater]

@soderlind The monthNames are in Dutch.

The file is Yes: acf-field-date-time-picker/js/localization/jquery-ui-timepicker-nl.js?ver=2.0.8

[soderlind]

Ok. I'm working with a fix for the date problem (converting between timestamp and the date / time format).

btw, which PHP version are you using ?

[dannykater]

My hosting is running on PHP 5.3.x.

Can i solve this temporarely by not using the timestamp format, but the date / time instead?

[soderlind]

Yes, not using the timestamp format should fix it. Date and time will be saved as a string in the same format you set when you created the field.

[dannykater]

Hmm, nice. Everything is working now!

Setting: Save as timestamp? NO. (Language and installation are NL.) No more Fatal Error and front end in good language.

Good luck with solving the bug on timestamp and other languages than English.

Thanks for the quick help.
