Title: Post editor "Visual / Html" tab problem Last modified: August 21, 2016 --- # Post editor "Visual / Html" tab problem * [salvatempe](https://wordpress.org/support/users/salvatempe/) * (@salvatempe) * [12 years, 5 months ago](https://wordpress.org/support/topic/post-editor-visual-html-tab-problem/) * Hi guys, I am Salvo from Italy. I’m facing this problem: when the plugin is enabled the post editor stuck on “Html” view. Any attempt to click to “Visual” tab button will ends in a javascript error: “Uncaught TypeError: Cannot read property ‘canvas’ of undefined” and the post stuck on html view. Disabling the plugin clean all errors. Are there any solutions? Any help is appreciated. Thanks. * [http://wordpress.org/plugins/magic-fields-2/](http://wordpress.org/plugins/magic-fields-2/) Viewing 1 replies (of 1 total) * Thread Starter [salvatempe](https://wordpress.org/support/users/salvatempe/) * (@salvatempe) * [12 years, 5 months ago](https://wordpress.org/support/topic/post-editor-visual-html-tab-problem/#post-4328675) * It seems that the problem may be fixed deleting the file /admin/mf_tiny_mce.php in plugin directory. Is that safe or may break something?
