I analysed the record in the database and date/time notation has changed from i: to O: All the O: records generate the issue. * Changing the date/time format in the basic settings does not change anything. * IMHO this is the cause of the issue: 2.5.5 (2022-03-29) Updated to timezone based date/time handling throughout the plugin, to have more consistent behaviour for all users, irrespective of their timezone/server. * I’ve put the 2.5.4 version back and the new reservations have the i: date format and cause no problem. The records with the O: format keep displaying with errors. * ``` s:15:\"date_submission\" i:1648463638 s:16:\"consent_acquired\" b:1 }'), s:15:\"date_submission\" i:1648541330 s:16:\"consent_acquired\" b:1 }'), s:15:\"date_submission\" i:1648586678 s:16:\"consent_acquired\" b:1 }'), s:15:\"date_submission\" O:8:\"DateTime\":3:{s:4:\"date\" s:26:\"2022-03-31 11:59:28.735484\" s:13:\"timezone_type\" i:3 s:8:\"timezone\" s:15:\"Europe/Brussels\" }s:16:\"consent_acquired\" b:1 }'), s:15:\"date_submission\" O:8:\"DateTime\":3:{s:4:\"date\" s:26:\"2022-03-31 15:48:05.171640\" s:13:\"timezone_type\" i:3 s:8:\"timezone\" s:15:\"Europe/Brussels\" }s:16:\"consent_acquired\" b:1 }'), s:15:\"date_submission\" O:8:\"DateTime\":3:{s:4:\"date\" s:26:\"2022-03-31 21:20:15.558907\" s:13:\"timezone_type\" i:3 s:8:\"timezone\" s:15:\"Europe/Brussels\" }s:16:\"consent_acquired\" b:1 }'), ``` - This reply was modified 4 years, 2 months ago by [M-iT](https://wordpress.org/support/users/demodirk/). - This reply was modified 4 years, 2 months ago by [M-iT](https://wordpress.org/support/users/demodirk/). - This reply was modified 4 years, 2 months ago by [M-iT](https://wordpress.org/support/users/demodirk/). * [M-iT](https://wordpress.org/support/users/demodirk/) * (@demodirk) * [4 years, 2 months ago](https://wordpress.org/support/topic/plugin-error-192/#post-15515742) * Temp solution: put version 2.5.4 back.
