Title: Uncaught exception: DateTime::__construct() Last modified: August 21, 2016 --- # Uncaught exception: DateTime::__construct() * Resolved [ditler](https://wordpress.org/support/users/ditler/) * (@ditler) * [11 years, 11 months ago](https://wordpress.org/support/topic/uncaught-exception-datetime_construct/) * Hey everyone, * I have a strange issue here, and no idea where it came from: * When I show the amr events lists widget to a logged in user, I get the error below. This does not occur for logged-out users nor on a special events page. * I use the amr-pluggable extension, but it works correctly and can be ruled out as the origin of the problem (persists even when pluggable plugin deactivated). * My timezone is set correctly and the plugin does recognize it, I guess. It says _Current time (unlocalised): Fri, 27 Jun 2014 12:38:08 +0200_ when my time is 12:38 in German time. * Thank you! * The error message: * ``` Uncaught exception: DateTime::__construct() [datetime.--construct]: Failed to parse time string (Do 26 Jun 2014 13:15:17 UTC) at position 0 (D): The timezone could not be found in the database An error in the input data may prevent correct display of this page. Please advise the administrator as soon as possible. ``` * [https://wordpress.org/plugins/amr-ical-events-list/](https://wordpress.org/plugins/amr-ical-events-list/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [anmari](https://wordpress.org/support/users/anmari/) * (@anmari) * [11 years, 11 months ago](https://wordpress.org/support/topic/uncaught-exception-datetime_construct/#post-5047949) * Hi that does sound weird – widget shouldn’t care whether a user is logged in or not. And uses much of the same code as the short odd. The only thing I can think of is that something else is interfering and/OR that the order of execution is causing a difference. * Try in a default wordpress theme or in a footer sidebar and see if that is any different. * There was a recent change with timezone BUT nothing to do with logged in/not logged in. Unless you have a plugin that sets time by user timezone ? * Thread Starter [ditler](https://wordpress.org/support/users/ditler/) * (@ditler) * [11 years, 11 months ago](https://wordpress.org/support/topic/uncaught-exception-datetime_construct/#post-5047987) * For one reason or another, after two days, the problem just disappeared. Maybe, after all, it does have something to do with caching in some sense, or maybe there was just a temporary issue with the icals from google. * The only downside: I will not be able to analyze the issue further. * Thanks however for your quick reaction! * Thread Starter [ditler](https://wordpress.org/support/users/ditler/) * (@ditler) * [11 years, 11 months ago](https://wordpress.org/support/topic/uncaught-exception-datetime_construct/#post-5048037) * Hey! It appeared again. Does not seem to have anything to do with the login/ logout though. The problem appears e.g. here: [http://www.corps-arminia.de/veranstaltungen/](http://www.corps-arminia.de/veranstaltungen/) I had suspected Total Cache and Widget Logic plugins, but deactivating them does not change anything. Also with Twenty Twelve clean theme the problem persists.

I cannot create the problem myself, not even on a german version with your ics file [http://lang.icalevents.com/kommende-veranstaltungen/?lang=de](http://lang.icalevents.com/kommende-veranstaltungen/?lang=de) * It seems to me that it is complaining about an a expanded/ translated current date and time string. However in searching through the code, the plugin does not attempt to create a date like that anywhere. * It is possible that this is something unique to your site. as noted before it only seems to happen when the widget is in sidebar on the one page, not on other pages. Puzzling. * In the next update I have aded more exception traps to try to trap the fatal error that it is causing and handle it more graciously – perhaps that will shed some light. * I also googled the problem. I thought perhaps it was a non-english language related issue but could not find much helpful. There are other php sites that report similar messages where the cause/solution appears to have nothing to do with datetime. * EG some joomla sites report similar errors and it appears to be totally unrelated folder permissions error, unwriteable directories. * [http://www.alfystudio.com/blog/91-joomla-3-error.html](http://www.alfystudio.com/blog/91-joomla-3-error.html) [http://vineetsaini.wordpress.com/2014/04/23/0-datetime__construct-datetime-construct-failed-to-parse-time-string-jerror-at-position-0-j-the-timezone-could-not-be-found-in-the-database/](http://vineetsaini.wordpress.com/2014/04/23/0-datetime__construct-datetime-construct-failed-to-parse-time-string-jerror-at-position-0-j-the-timezone-could-not-be-found-in-the-database/) [http://stackoverflow.com/questions/16632546/joomla-installing-new-language-datetime-construct-failed-to-parse-time-str](http://stackoverflow.com/questions/16632546/joomla-installing-new-language-datetime-construct-failed-to-parse-time-str) * mysql driver error?

Again, the problem only appeared when logged in, and only on the events page. However, I have corrected some code for widget logic now, so that the widget is not shown on events page (which is how it was supposed in the first place and worked in former days). So, for me the problem is solved, though I do not know what caused it. It seems like the two instances (the main view is a lit-type 1, widget list-type 2 via pluggable-plugin) interfere with each other? * Thanks for your effort! * Thread Starter [ditler](https://wordpress.org/support/users/ditler/) * (@ditler) * [11 years, 11 months ago](https://wordpress.org/support/topic/uncaught-exception-datetime_construct/#post-5048042) * After all, it seems to have something to do with my pluggable plugin: * ``` '; for ($i=$von; $i<$bis_exkl; $i++) { $event = $events[$i]; // DESIGN ANFANG if($event['URL'][0]!='') { $spalteo .= ''; } $spalteo .= '

The scenarios might be quite different. If you think they are the same you could link to this one. * These sort of problems are usually caused by either 1) your own code introducing problems – eg passing a string like ‘jue 09 oct 2014 10:15:24 UTC’ to a date time contruct statement – that will not work or 2) data in the ics file you are using and you have not provided that. * Please start a new topic and provide the ics url’s you are using. It might also be a good idea to say which list type and/or which fields you are trying to display. If you have written any custom code that may be affecting it, please eactivate that to debug whether that is causing the problem.
