But when clicking next or insert the url directly in the browser it messes up the order. When you go to http://www.hp-sidecarparts.eu/hp-servicekalender/ it shows the right order. But on clicking “volgende evenemten” it looks like it reverses the order of the months and events. When you refresh the page again, the order is correct.
Looks to me that the PHP is working fine, but the AJAX load is missing something.
Have you encountered this issue before? And is there any way to fix this?
Would you mind logging in so I can verify your support access? Or, if you don’t have/want a license (which includes a year of support) you should checkout the volunteer community on WordPress.org: The Events Calendar. It’s not the same level of support, but it’s free! We even check those forums once each week and help to the extent we can.
Once you’ve logged in, would you mind answering the following questions?
Do you have any customizations on your site, perhaps a snippet we provided in our Knowledgebase?
