    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:

    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,
    , 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

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

    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?

    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=¨¨»«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

    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.
