Equations not showing on the website and when I tried to open them from the equation editor remains a blank/white screen.

Wiris Editor is not working. It’s showing trail is expired please fix this. I’m Using Equation Editor Pro

I have discovered that the equation editor no longer works. I cannot create new equations (the popup window just stays blank/empty), I cannot edit existing equations (still an empty/blank popup window), and the existing equations only shows the short codes on the page, and broken image links in the Gutenberg editor.

Hello,

When using a regular JS call for loading tinyMCE what settings do we need to add in order to have your tools shown in the editor?

Here is an example call that does not load it:

settings = {	
	    tinymce: {
	        wpautop  : true,
	        theme    : 'modern',
	        skin     : 'lightgray',
	        language : 'en',
	        formats  : {
	            alignleft  : [
	                { selector: 'p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li', styles: { textAlign: 'left' } },
	                { selector: 'img,table,dl.wp-caption', classes: 'alignleft' }
	            ],
	            aligncenter: [
	                { selector: 'p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li', styles: { textAlign: 'center' } },
	                { selector: 'img,table,dl.wp-caption', classes: 'aligncenter' }
	            ],
	            alignright : [
	                { selector: 'p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li', styles: { textAlign: 'right' } },
	                { selector: 'img,table,dl.wp-caption', classes: 'alignright' }
	            ],
	            strikethrough: { inline: 'del' }
	        },
	        relative_urls       : false,
	        remove_script_host  : false,
	        convert_urls        : false,
	        browser_spellcheck  : true,
	        fix_list_elements   : true,
	        entities            : '38,amp,60,lt,62,gt',
	        entity_encoding     : 'raw',
	        keep_styles         : false,
	        paste_webkit_styles : 'font-weight font-style color',
	        preview_styles      : 'font-family font-size font-weight font-style text-decoration text-transform',
	        tabfocus_elements   : ':prev,:next',
	        plugins    : 'charmap,hr,media,paste,tabfocus,textcolor,fullscreen,wordpress,wpeditimage,wpgallery,wplink,wpdialogs,wpview',
	        resize     : 'vertical',
	        menubar    : false,
	        indent     : false,
	        toolbar1   : 'bold,italic,strikethrough,bullist,numlist,blockquote,hr,alignleft,aligncenter,alignright,link,unlink,wp_more,spellchecker,fullscreen,wp_adv',
	        toolbar2   : 'formatselect,underline,alignjustify,forecolor,pastetext,removeformat,charmap,outdent,indent,undo,redo,wp_help',
	        toolbar3   : '',
	        toolbar4   : '',
	        body_class : 'id post-type-post post-status-publish post-format-standard',
	        wpeditimage_disable_captions: false,
	        wpeditimage_html5_captions  : true
	
	    },
	    quicktags   : true,
	    mediaButtons: true
	
	}
	wp.editor.initialize(textareaID, settings);

When I click fx button in wordpress editor, popup starts and equation is created but the button to insert the equation into post is not shown.

I purchased the Pro version of the Equation Editor. However, sadly I found out that the plugin does not work with instances of the classic editor in the front end (for instance, user’s comments). I have been trying to contact the developer with no success.

Please, I may need some personalised service because it’s important for me that the plugin works with the front end editors because my site is entirely maths based.

Please contact me through nobillionaire(at)gmail(dot)com

NB: Please change the ‘(at)’ to ‘@’ and ‘(dot)’ to ‘.’ in the email.

Thanks and regards.

Hi

I had an error, where Equation editor prevented a post from being saved.
Edit the two lines in /wp-content/plugins/equation-editor/tiny_mce_wiris/integration/lib/php/Boot.class.php:

Line 834 should read: $qname = ($bn == ‘HList’ && empty($pack)) ? ‘List’ : join(‘.’, array_merge($pack, array($bn)));

Line 840 should be: ‘phpname’ => join(‘_’, array_merge($pack, array($prefix . $bn)))

I am unable to save after writing in Equation Editor. I brought a pro version of this. I am unable to get any support from the designer.
The chemistry option is also not working. I am using LearnDash LMS plugin inside wordpress.

Anybody please help.

How do i need to do?

Hi
I’m trying to use this plugin and I’m facing a problem. Although the WIRIS Editor is working, it seems that equations are not properly converted to images because in the blog they are still displayed the classic raw (ugly) way, if you know what I mean.

I’m using the gutemberg editor and switching to the classic editor in order to display the wiris one.

Thanks
Denis

Hi,
The plugin is working fine in post content when disabling wpautop.
but the same thing is not working in post comment. i don’t know how to disable wpautop for comments. pl help me.

In PHP 7.4, the implode() function now throws an exception when passing the glue and pieces in the wrong order.

This causes line 2732 of /equation-editor-fork/tiny_mce_wiris/core/core.js to fail because it sees a PHP warning string rather than a valid JSON string.

Here’s the error:

"<pre>uncaught exception: <b>join(): Passing glue string after array is deprecated. Swap the parameters (errno: 8192) in /home/public_html/wp-content/plugins/equation-editor-fork/tiny_mce_wiris/integration/lib/php/Boot.class.php at line #835join(): Passing glue string after array is deprecated.

#6 /home/public_html/wp-content/plugins/equation-editor-fork/tiny_mce_wiris/integration/configurationjs.php(5): require_once('/home/...')
#7 {main}</pre>"

As a result of this, the TinyMCE editor (Classic Editor) breaks and can’t swap between modes or save correctly.

Hi

Hope it will be fixed soon.

Hello,

Thank you for giving us this plugin and make our authors’ life easier. We really appreciate it. However, it is really hard for us to stick with the old tinyMCE editor. Can you please add support for the latest Block Editor of WordPress 5.4? It will be really helpful for our authors.

Thank you.

Hi Gents,

i use this plugin within Discy theme , i add the code :

<script>window.MathJax = { MathML: { extensions: ["mml3.js", "content-mathml.js"]}};</script>
<script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=MML_HTMLorMML"></script>

on the header of theme but still dont show in the front-end

Yesterday morning CET, March 11,2020, for several hours, all the equations of the linked page
were set as invalid equation [ redundant link removed ]
Please clarify the reason (the provider, aruba.it, claims the issue is not their)
and how to prevent.
Thanks

Great plugin. Wiris editor doesn’t work on chrome or IE (hence pointless) so I changed to Latex editor as suggested in different thread. That does work.
However:
Quotation marks seem to cause trouble.
Formula with “”, clicked insert into post, and got different results,
either – nothing was posted, empty result, had to start over from scratch
or – “invalid formula” symbol posted.
however the formula was correctly displayed in preview and I was able to generate a GIF from it successfully.
I put a formula without the quotation marks now and that worked.
Firefox 73.0.1, W10Pro64
Suggestion: Support editing formulas! You already store the source code of the formula in the alt text field, so when I click on a formula and then the fx button, I’d love to see that source code already pre-filled in the popup window so I can edit it!! But thats a separate thing and not a support request.
