Title: Uncaught Error: no such method 'instance' Last modified: August 22, 2016 --- # Uncaught Error: no such method 'instance' * Resolved [yuzairy](https://wordpress.org/support/users/yuzairy/) * (@yuzairy) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/) * Got this error in the edit post mode: * Uncaught Error: no such method ‘instance’ for menu widget instance [http://mydomain.dev/wp-admin/load-scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,utils,jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,jquery-ui-sortable,postbox,plupload,json2&ver=4.1](http://mydomain.dev/wp-admin/load-scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,utils,jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,jquery-ui-sortable,postbox,plupload,json2&ver=4.1) line 2 * Test environment: - WP version 4.1 fresh install - Theme: Twenty Fourteen * Active plugins: - Akismet v3.0.4 - WordPress SEO v1.7.1 - Membermouse v2.2.2 - Debug Bar v0.8.2 * It’s a 3 way conflict I think since I can only reproduce the error when ALL the above plugins active. Tested older Akismet versions and the error starts from Akismet v3.0.0-RC1 onwards. v2.6.0 is fine so hopefully that somewhat helps you to troubleshoot. * I can give access to my test site (since membermouse is a premium plugin) but not sure how to pass the login short of putting it in public. * [https://wordpress.org/plugins/akismet/](https://wordpress.org/plugins/akismet/) Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Contributor [Greg](https://wordpress.org/support/users/jgs/) * (@jgs) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707399) * Can you try enabling debug on your site, and send in the logs through our contact form? * Here’s how to get debug enabled: [http://docs.akismet.com/general/how-do-i-debug-the-akismet-plugin/](http://docs.akismet.com/general/how-do-i-debug-the-akismet-plugin/) * And our contact form: [https://akismet.com/contact](https://akismet.com/contact) * [majato](https://wordpress.org/support/users/majato/) * (@majato) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707431) * Hi – I was just about to raise a bug when I noticed this looks like the same problem I am having. I think the problem I’m experiencing is between It looks like Akismet 3.0.4 and WordPress SEO 1.7.1. Happy to run the Debug too if it helps you resolve this issue. * Thread Starter [yuzairy](https://wordpress.org/support/users/yuzairy/) * (@yuzairy) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707435) * Tried to turn on debug but it’s not generating the debug.log 🙁 I’ve send my login via the contact form if you want to look at it. * The error is not breaking anything but it’s something that you may want to look. * [majato](https://wordpress.org/support/users/majato/) * (@majato) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707436) * Hi Yuzairy. * I added this to my wp.config file (make sure it appears before ” /* That’s all, stop editing! Happy blogging. */ “) * */ define(‘WP_DEBUG’, true); * define(‘WP_DEBUG_LOG’, true); * // Disable display of errors and warnings define(‘WP_DEBUG_DISPLAY’, false); @ini_set(‘display_errors’,0); * I wasn’t seeing a debug file at first either, but I found if I went to the Akismet plugin (on your WordPress site’s installed plugins) then put [http://www.yoursite.com/wp-content/debug.log](http://www.yoursite.com/wp-content/debug.log) in the browser and I could see the debug log. * Plugin Author [Christopher Finke](https://wordpress.org/support/users/cfinke/) * (@cfinke) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707441) * [@yuzairy](https://wordpress.org/support/users/yuzairy/): I have confirmed that I can reproduce the error on your site when only Akismet, WordPress SEO, and MemberMouse are active. Debug Bar doesn’t seem to be involved. * I am 99% sure the error is occurring because MemberMouse includes its own version of jQuery UI (which it should not do), and it’s conflicting with the version of jQuery UI that is already included by core. MemberMouse also does some other things (like `var $ = jQuery;` in `global.js`) that could already be causing problems or will cause problems eventually. You should contact them about fixing that up. * Plugin Author [Christopher Finke](https://wordpress.org/support/users/cfinke/) * (@cfinke) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707442) * [@majato](https://wordpress.org/support/users/majato/): I can’t reproduce with just Akismet and WordPress SEO; what other plugins do you have installed? * [majato](https://wordpress.org/support/users/majato/) * (@majato) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707443) * Loads……..Contact Form 7, CSS3 Responsive Web Pricing Tables Grids, Dynamic Vouchers, GT-Vouchers, Simple Ads Manager, Social Connect, TPC! Memory Usage, Ubermenu 2, W3 Total Cache, WP Smush.It. * I have tried deactivating them all except Akismet and WordPress SEO, however, the error still occurs (of course, if I only have WordPress SEO active the bug does not occur.) * I sent a dubug file earlier. * Thread Starter [yuzairy](https://wordpress.org/support/users/yuzairy/) * (@yuzairy) * [11 years, 4 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707446) * [@cfinke](https://wordpress.org/support/users/cfinke/): Thanks! Will pass the message to them. * [@majato](https://wordpress.org/support/users/majato/): I didn’t see any error with Akismet + WordPress SEO activated either on my vanilla install. * [psorensen](https://wordpress.org/support/users/psorensen/) * (@psorensen) * [11 years, 3 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707489) * [@yuzairy](https://wordpress.org/support/users/yuzairy/): Have you heard anything back on this matter? I’ve recently experienced this same issue. I contacted Membermouse about the issue, but they don’t seem to think there’s anything wrong. * [thehollyhopdrive](https://wordpress.org/support/users/thehollyhopdrive/) * (@thehollyhopdrive) * [11 years, 3 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707506) * I’ve found that the patch mentioned by Nigel Fish in [this thread](https://wordpress.org/support/topic/javascript-error-with-wp-version-41) works in the interim until a proper patch has been applied. * Plugin Author [Christopher Finke](https://wordpress.org/support/users/cfinke/) * (@cfinke) * [10 years, 11 months ago](https://wordpress.org/support/topic/uncaught-error-no-such-method-instance/#post-5707522) * Marking as resolved, since the problem lies in another plugin and is being addressed in that support forum.
