Title: [Plugin: WP Calendar] Problem with Java and Ajax Last modified: August 19, 2016 --- # [Plugin: WP Calendar] Problem with Java and Ajax * Resolved [Ymmmot](https://wordpress.org/support/users/ymmmot/) * (@ymmmot) * [15 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-calendar-problem-with-java-and-ajax/) * When I am in the preferences of wp-calendar or writing a new post, the media- buttons (add picture/video/…) dont run. And I can’t enter a tag, too. I think its a Java-Ajax-problem, but I dont really know.

It crashes my whole blog! No way to run JQuery. Nothing run… * Plugin Author [faebu](https://wordpress.org/support/users/faebu/) * (@faebu) * [15 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-calendar-problem-with-java-and-ajax/#post-1960876) * > It crashes my whole blog! * what crashes? a few more details would be great. * wp calendar uses some javascript libraries, which could cause your problems. But, all the basic libraries (like jQuery) aren’t loaded directly, but loaded the safe and recommended way. * this sounds more like a conflict with another plug-in or your theme which does not load the libraries, how it should and how it’s recommended. * Thread Starter [Ymmmot](https://wordpress.org/support/users/ymmmot/) * (@ymmmot) * [15 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-calendar-problem-with-java-and-ajax/#post-1960877) * As I said. Can’t write tags, the “add-media-buttons” at the top of text-field( where you write a post) don’t work. When I am in the preferences-wp-calendar, I can’t click on the little arrows next to the other links (like “Users”, “Plugins”,“ Tools” etc.)… There are the plugins I use: [link](http://goo.gl/zWkvH). * Plugin Author [faebu](https://wordpress.org/support/users/faebu/) * (@faebu) * [15 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-calendar-problem-with-java-and-ajax/#post-1960878) * does it work, when deactivating wp calendar plugin? does it work, when deactivating all plug-ins expect the wp calendar plugin? * Thread Starter [Ymmmot](https://wordpress.org/support/users/ymmmot/) * (@ymmmot) * [15 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-calendar-problem-with-java-and-ajax/#post-1960879) * > does it work, when deactivating wp calendar plugin? * Yes. * > does it work, when deactivating all plug-ins expect the wp calendar plugin? * Dunno.

I downloaded the new version and activated it again, but the buttons don’t work. * I will try something for you. I’m going to download: [http://www.usbwebserver.net/](http://www.usbwebserver.net/).. On this server I’m also going to install wordpress and (only) WP Calender. Maybe my hosting is the problem. * I keep you posted! * [naffets92](https://wordpress.org/support/users/naffets92/) * (@naffets92) * [15 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-calendar-problem-with-java-and-ajax/#post-1960983) * Okay, * This is very strange. A while ago I created a wordpress website with 3.0 (with usb webserver). I also use WP Calender. This works fine! * Okay well. Now I have upgraded this wordpress website to 3.1. The plugin WP calender: current version was 1.2.4. This works fine! The insert media buttons in a post work! * After that I upgraded the WP Calender plugin to the newest version.. The insert media buttons don’t work anymore. When I upgraded it, It gaves an announcement: I had to reactivate the plugin. * Now I am going to try the 1.2.4 version of your plugin on my wordpress 3.1 website. Maybe this will work.
