Moodle plugins directory: MathType filter by WIRIS

Hello,
I'm currently migrating from Moodle 2.8 to Moodle 3.2.
And the filter_wiris plugin poses a problem during the migration.
I get this error:

filter_wiris
Erreur d'exécution DDL sql
Erreur: 1071 Specified key was too long
CREATE TABLE mdl_filter_wiris_formulas (
id BIGINT(10) NOT NULL auto_increment,
md5 VARCHAR(255) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '',
content LONGTEXT COLLATE utf8mb4_unicode_ci NOT NULL,
CONSTRAINT PRIMARY KEY (id)
, UNIQUE KEY mdl_filtwiriform_md5_uix (md5)
)
ENGINE = InnoDB
DEFAULT COLLATE = utf8mb4_unicode_ci ROW_FORMAT=Dynamic
Error code: ddlexecuteerror

Has anyone ever faced this mistake?

Thank you

Hello @Loi

We have checked 2.8 --> 3.2 migration and we can't reproduce your issue.

Your problem seems related to your DB configuration. Please write us at support@wiris.com so we can better help you.

Thanks for your feedback,

@Loi

Reviewing your issue we detect a bug with utfmb4 collation. We are working to solve it in our next release.

Hello, I installed the wiris filter and math editor. When I enable filter, I see (moodle 2.5) :

Thanks for your feedback

@Дмитрий Александрович Штырлин

We can't reproduce your issue in our end (installing 4.3.1 version on a Moodle 2.5)

Your problem seems related to your end configuration. Please write us at support@wiris.com so we can better help you.

This plugin is absolutely outstanding. Thank you. Installed on Moodle 3.3.2 with 0 problems.

@Andrew Normore: Thank you very much for your feedback, we really appreciated it!

I am trying to find out if the WIRIS chemistry editor meets WCAG 2.0 accessibility. Anyone know?

Dear..
wiris math and chemistry are activated in my moodle 3.2, it was working with both editor atto and MCE HTml , suddenly it's stopped working, we you press on it it's give me a blank page without any symblos, we are in university and the students need it to use the equztions.. please help

@may aldanee Please contact us at support@wiris.com and provide us the URL of your Moodle instance. Thanks!

We've got a puzzling issue here.

When a student does an Online Text assignment submission that uses Wiris math markup, the markup source code shows in the instructor's view (grading page) for that assignment. Likewise, when the instructor looks at the assignment submission individually, the markup source code shows, abbreviated, until the instructor clicks the "+" button, at which point the rendered image of the math symbols is displayed. This started happening in Moodle 3.5 and did not occur in 3.4 and previous.

Any ideas?

While exporting Wiris MathType question didn't shows question it shows links.
How to export mathtype question in offline quiz?

Dear Sir/madam,
We tried Wiris MathType and We create some Math questions in Moodle.
It's working smoothly for Online quiz. But that questions we export questions its shows encrypted questions(We couldn't export question properly.)

It;s shows like.

a) «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mn»20«/mn»«mn»0«/mn»«/msup»«mi»C«/mi»«mo»§#160;«/mo»«mi»t«/mi»«mi»o«/mi»«mo»§#160;«/mo»«msup»«mn»40«/mn»«mn»0«/mn»«/msup»«mi»C«/mi»«/math»

When we export questions It's shows like above statement.

Rahul, that is expected behaviour and filter_wiris will take care of rendering that. Find more info on the encoding at
https://docs.wiris.com/en/mathtype/mathtype_web/integrations/encoding-attributes

We are working on extending HTMLpurifier to include MathML tags.

Since we already got a couple of your messages through proper support channels, let's follow the communication there for any extra info you might need.
