Or if you want me to start a new thread let me know. * I am also having the same issue. I am currently using PHP version: 5.4.45 – used Jonathan’s code from this page to remove the json_encode and it seemed to have cleared up: [https://ideas.time.ly/ideas/CAL-I-432](https://ideas.time.ly/ideas/CAL-I-432). Not sure what if any impact there is by taking the code out, so wondering if that’s okay. Before changing the code I also did a reinstall WordPress 4.8.2. Dashboard, Updates, Re-install Now. That didn’t help and continued getting the error, hence the code change. * Thanks for any insight. - This reply was modified 8 years, 8 months ago by [skippywp](https://wordpress.org/support/users/skippywp/). Reason: Needed to update the issue * [skippywp](https://wordpress.org/support/users/skippywp/) * (@skippywp) * [8 years, 8 months ago](https://wordpress.org/support/topic/warning-http_build_query-3/#post-9574878) * Okay, I think I found the answer. As mentioned above, the PHP version was 5.4.45. I found a clue about upgrading the PHP version to 5.6+: [https://wordpress.org/support/topic/fatal-error-arrays-are-not-allowed-in-class-constants/](https://wordpress.org/support/topic/fatal-error-arrays-are-not-allowed-in-class-constants/) * I upgraded the PHP version to 5.6+, put back the json_encode code back into the file and cleared cached. Tested, and I am not seeing the error right now. Hurray! * I believe the answer is upgrade the PHP to 5.6+. * [Benjamin](https://wordpress.org/support/users/bsokic/) * (@bsokic) * [8 years, 8 months ago](https://wordpress.org/support/topic/warning-http_build_query-3/#post-9576353) * [@skippywp](https://wordpress.org/support/users/skippywp/), I am glad you find a way through the issue 🙂 * [@kwooduwcv](https://wordpress.org/support/users/kwooduwcv/), please upgrade PHP if not already. * Take care, Ben * [skippywp](https://wordpress.org/support/users/skippywp/) * (@skippywp) * [8 years, 8 months ago](https://wordpress.org/support/topic/warning-http_build_query-3/#post-9585264) * Although I thought upgrading the PHP to 5.6.30 fixed the issue, but when I logged into the site today and wanted to add a new event, the error was back on the “ page”: /wp-admin/post-new.php?post_type=ai1ec_eventdetails. * The error: Warning: http_build_query(): Parameter 1 expected to be Array or Object. Incorrect value given in /wp-includes/Requests/Transport/cURL.php on line 508 * It hasn’t impacted the site as far as I can tell, but it would be helpful to know of any other suggestions to clear this up. * Thanks, Skippywp Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘Warning: http_build_query()’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/all-in-one-event-calendar.svg) * [Timely All-in-One Events Calendar](https://wordpress.org/plugins/all-in-one-event-calendar/) * [Support Threads](https://wordpress.org/support/plugin/all-in-one-event-calendar/) * [Active Topics](https://wordpress.org/support/plugin/all-in-one-event-calendar/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/all-in-one-event-calendar/unresolved/) * [Reviews](https://wordpress.org/support/plugin/all-in-one-event-calendar/reviews/) ## Tags * [AIOEC](https://wordpress.org/support/topic-tag/aioec/) * [warning](https://wordpress.org/support/topic-tag/warning/) * 5 replies * 3 participants * Last reply from: [skippywp](https://wordpress.org/support/users/skippywp/) * Last activity: [8 years, 8 months ago](https://wordpress.org/support/topic/warning-http_build_query-3/#post-9585264) * Status: resolved
